PyInstaller Overview

PyPI PyPI - Python Version Read the Docs (version) PyPI - Downloads

PyInstaller bundles a Python application and all its dependencies into a single package. The user can run the packaged app without installing a Python interpreter or any modules.

Documentation: https://pyinstaller.org/
Code: https://github.com/pyinstaller/pyinstaller

PyInstaller reads a Python script written by you. It analyzes your code to discover every other module and library your script needs in order to execute. Then it collects copies of all those files -- including the active Python interpreter! -- and puts them with your script in a single folder, or optionally in a single executable file.

PyInstaller is tested against Windows, macOS, and GNU/Linux. However, it is not a cross-compiler: to make a Windows app you run PyInstaller in Windows; to make a GNU/Linux app you run it in GNU/Linux, etc. PyInstaller has been used successfully with AIX, Solaris, FreeBSD and OpenBSD, but is not tested against them as part of the continuous integration tests.

Main Advantages

  • Works out-of-the-box with any Python version 3.8-3.12.
  • Fully multi-platform, and uses the OS support to load the dynamic libraries, thus ensuring full compatibility.
  • Correctly bundles the major Python packages such as numpy, PyQt5, PySide2, PyQt6, PySide6, wxPython, matplotlib and others out-of-the-box.
  • Compatible with many 3rd-party packages out-of-the-box. (All the required tricks to make external packages work are already integrated.)
  • Works with code signing on macOS.
  • Bundles MS Visual C++ DLLs on Windows.

Installation

PyInstaller is available on PyPI. You can install it through pip:

pip install pyinstaller

Requirements and Tested Platforms

  • Python:
    • 3.8-3.12. Note that Python 3.10.0 contains a bug making it unsupportable by PyInstaller. PyInstaller will also not work with beta releases of Python 3.13.
  • Windows (32bit/64bit/ARM64):
    • PyInstaller should work on Windows 7 or newer, but we only officially support Windows 8+.
    • Support for Python installed from the Windows store without using virtual environments requires PyInstaller 4.4 or later.
  • Linux:
    • GNU libc based distributions on architectures x86_64, aarch64, i686, ppc64le, s390x.
    • musl libc based distributions on architectures x86_64, aarch64.
    • ldd: Console application to print the shared libraries required by each program or shared library. This typically can be found in the distribution-package glibc or libc-bin.
    • objdump: Console application to display information from object files. This typically can be found in the distribution-package binutils.
    • objcopy: Console application to copy and translate object files. This typically can be found in the distribution-package binutils, too.
    • Raspberry Pi users on armv5-armv7 should add piwheels as an extra index url then pip install pyinstaller as usual.
  • macOS (x86_64 or arm64):
    • macOS 10.15 (Catalina) or newer.
    • Supports building universal2 applications provided that your installation of Python and all your dependencies are also compiled universal2.

Usage

Basic usage is very simple, just run it against your main script:

pyinstaller /path/to/yourscript.py

For more details, see the manual.

Untested Platforms

The following platforms have been contributed and any feedback or enhancements on these are welcome.

  • FreeBSD
    • ldd
  • Solaris
    • ldd
    • objdump
  • AIX
    • AIX 6.1 or newer. PyInstaller will not work with statically linked Python libraries.
    • ldd
  • Linux on any other libc implementation/architecture combination not listed above.

Before using any contributed platform, you need to build the PyInstaller bootloader. This will happen automatically when you pip install pyinstaller provided that you have an appropriate C compiler (typically either gcc or clang) and zlib's development headers already installed.

================================ The PyInstaller licensing terms ================================ Copyright (c) 2010-2023, PyInstaller Development Team Copyright (c) 2005-2009, Giovanni Bajo Based on previous work under copyright (c) 2002 McMillan Enterprises, Inc. PyInstaller is licensed under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. Bootloader Exception -------------------- In addition to the permissions in the GNU General Public License, the authors give you unlimited permission to link or embed compiled bootloader and related files into combinations with other programs, and to distribute those combinations without any restriction coming from the use of those files. (The General Public License restrictions do apply in other respects; for example, they cover modification of the files, and distribution when not linked into a combined executable.) Bootloader and Related Files ---------------------------- Bootloader and related files are files which are embedded within the final executable. This includes files in directories: ./bootloader/ ./PyInstaller/loader Run-time Hooks ---------------------------- Run-time Hooks are a different kind of files embedded within the final executable. To ease moving them into a separate repository, or into the respective project, these files are now licensed under the Apache License, Version 2.0. Run-time Hooks are in the directory ./PyInstaller/hooks/rthooks The PyInstaller.isolated submodule ---------------------------------- By request, the PyInstaller.isolated submodule and its corresponding tests are additionally licensed with the MIT license so that it may be reused outside of PyInstaller under GPL 2.0 or MIT terms and conditions -- whichever is the most suitable to the recipient downstream project. Affected files/directories are: ./PyInstaller/isolated/ ./tests/unit/test_isolation.py About the PyInstaller Development Team -------------------------------------- The PyInstaller Development Team is the set of contributors to the PyInstaller project. A full list with details is kept in the documentation directory, in the file ``doc/CREDITS.rst``. The core team that coordinates development on GitHub can be found here: https://github.com/pyinstaller/pyinstaller. As of 2021, it consists of: * Hartmut Goebel * Jasper Harrison * Bryan Jones * Brenainn Woodsend * Rok Mandeljc Our Copyright Policy -------------------- PyInstaller uses a shared copyright model. Each contributor maintains copyright over their contributions to PyInstaller. But, it is important to note that these contributions are typically only changes to the repositories. Thus, the PyInstaller source code, in its entirety is not the copyright of any single person or institution. Instead, it is the collective copyright of the entire PyInstaller Development Team. If individual contributors want to maintain a record of what changes/contributions they have specific copyright on, they should indicate their copyright in the commit message of the change, when they commit the change to the PyInstaller repository. With this in mind, the following banner should be used in any source code file to indicate the copyright and license terms: #----------------------------------------------------------------------------- # Copyright (c) 2005-2023, PyInstaller Development Team. # # Distributed under the terms of the GNU General Public License (version 2 # or later) with exception for distributing the bootloader. # # The full license is in the file COPYING.txt, distributed with this software. # # SPDX-License-Identifier: (GPL-2.0-or-later WITH Bootloader-exception) #----------------------------------------------------------------------------- For run-time hooks, the following banner should be used: #----------------------------------------------------------------------------- # Copyright (c) 2005-2023, PyInstaller Development Team. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # # The full license is in the file COPYING.txt, distributed with this software. # # SPDX-License-Identifier: Apache-2.0 #----------------------------------------------------------------------------- ================================ GNU General Public License ================================ https://gnu.org/licenses/gpl-2.0.html GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
