PyInstaller bundles a Python application and all its dependencies into a single package.
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.
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, Mac OS X, and Linux. However, it is not a cross-compiler: to make a Windows app you run PyInstaller in Windows; to make a Linux app you run it in Linux, etc. PyInstaller has been used successfully with AIX, Solaris, and FreeBSD, but is not tested against them.
- Works out-of-the-box with any Python version 2.7 / 3.3-3.5.
- 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, PyQt4, PyQt5, PySide, Django, 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.)
- Libraries like PyQt5, PyQt4, PySide, wxPython, matplotlib or Django are fully supported, without having to handle plugins or external data files manually.
- Working code signing on OS X.
- Bundles MS Visual C++ DLLs on Windows.
PyInstaller is available on PyPI. You can install it through pip:
pip install pyinstaller
Requirements and Tested Platforms
- 2.7 or 3.3+
- PyCrypto 2.4+ (only if using bytecode encryption)
- Windows (32bit/64bit):
- Windows XP or newer.
- Linux (32bit/64bit)
- 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.
- Mac OS X (64bit):
- Mac OS X 10.6 (Snow Leopard) or newer.
Basic usage is very simple, just run it against your main script:
For more details, see the manual.
The following platforms have been contributed and any feedback or enhancements on these are welcome.
- AIX 6.1 or newer. PyInstaller will not work with statically linked Python libraries.
Before using any contributed platform, you need to build the PyInstaller bootloader, as we do not ship binary packages. Download PyInstaller source, and build the bootloader:
cd bootloader python ./waf distclean all
Then install PyInstaller:
python setup.py install
or simply use it directly from the source (pyinstaller.py).

- Fix weird “missing symbol” errors under Mac OSX (thanks to Isaac Wagner).
- Fully support up to Python 2.6 on Linux/Mac and Python 2.5 on Windows.
- Preliminar Mac OSX support: both one-file and one-dir is supported; for non-console applications, a bundle can be created. Thanks to many people that worked on this across several months (Daniele Zannotti, Matteo Bertini, Lorenzo Mancini).
- Improved Linux support: generated executables are fatter but now should now run on many different Linux distributions (thanks to David Mugnai).
- Add support for specifying data files in import hooks. PyInstaller can now automatically bundle all data files or plugins required for a certain 3rd-party package.
- Add intelligent support for ctypes: PyInstaller is now able to track all places in the source code where ctypes is used and automatically bundle dynamic libraries accessed through ctypes. (Thanks to Lorenzo Mancini for submitting this). This is very useful when using ctypes with custom-made dynamic libraries.
- Executables built with PyInstaller under Windows can now be digitally signed.
- Add support for absolute imports in Python 2.5+ (thanks to Arve Knudsen).
- Add support for relative imports in Python 2.5+.

- Add support for .egg files: PyInstaller is now able to look for dependencies within .egg files, bundle them and make them available at runtime with all the standard features (entry-points, etc.).
- Add partial support for .egg directories: PyInstaller will treat them as normal packages and thus it will not bundle metadata.
- Under Linux/Mac, it is now possible to build an executable even when a system packages does not have .pyc or .pyo files available and the system-directory can be written only by root. PyInstaller will in fact generate the required .pyc/.pyo files on-the-fly within a build-temporary directory.
- Add automatic import hooks for many third-party packages, including:
- PyQt4 (thanks to Pascal Veret), with complete plugin support.
- pyodbc (thanks to Don Dwiggins)

- Improved PyGTK (thanks to Marco Bonifazi and foxx).
- paste (thanks to Jamie Kirkpatrick)
- Add fix for the very annoying “MSVCRT71 could not be extracted” bug, which was caused by the DLL being packaged twice (thanks to Idris Aykun).
- Removed C++-style comments from the bootloader for compatibility with the AIX compiler.
- Fix support for .py files with DOS line endings under Linux (fixes PyOpenGL).
- Fix support for PIL when imported without top-level package (“import Image”).
- Fix PyXML import hook under NT (thanks to Lorenzo Mancini)
- Fixed problem with PyInstaller picking up the wrong copy of optparse.
- Improve correctness of the binary cache of UPX’d/strip’d files. This fixes problems when switching between multiple versions of the same third-party library (like e.g. wxPython allows to do).
- Fix a stupid bug with modules importing optparse (under Linux) (thanks to Louai Al-Khanji).
- Under Python 2.4+, if an exception is raised while importing a module inside a package, the module is now removed from the parent’s namespace (to match the behaviour of Python itself).
- Fix random race-condition at startup of one-file packages, that was causing this exception to be generated: “PYZ entry ‘encodings’ (0j) is not a valid code object”.
- Fix problem when having unicode strings among path elements.
- Fix random exception (“bad file descriptor”) with “prints” in non-console mode (actually a pythonw “bug” that’s fixed in Python 3.0).
- Sometimes the temporary directory did not get removed upon program exit, when running on Linux.
- Fixed random segfaults at startup on 64-bit platforms (like x86-64).
- Fix bug with user-provided icons disappearing from built executables when these were compressed with UPX.
- Fix problems with packaging of applications using PIL (that was broken because of a bug in Python’s import machinery, in recent Python versions). Also add a workaround including Tcl/Tk with PIL unless ImageTk is imported.
- (Windows) When used under Windows XP, packaged programs now have the correct look & feel and follow user’s themes (thanks to the manifest file being linked within the generated executable). This is especially useful for applications using wxPython.
- Fix a buffer overrun in the bootloader (which could lead to a crash) when the built executable is run from within a deep directory (more than 70-80 characters in the pathname).
- Bootstrap modules are now compressed in the executable (so that they are not visible in plaintext by just looking at it with a hex editor).
- Fixed a regression introduced in 1.1: under Linux, the bootloader does not depend on libpythonX.X.so anymore.
- Fix a crash when invoking UPX with certain kinds of builds.
- Fix icon support by re-adding a resource section in the bootloader executable.
- (Windows) Make single-file packages not depend on MSVCRT71.DLL anymore, even under Python 2.4. You can eventually ship your programs really as single-file executables, even when using the newest Python version!
- Fix problem with incorrect python path detection. Now using helpers from distutils.
- Fix problem with rare encodings introduced in newer Python versions: now all the encodings are automatically found and included, so this problem should be gone forever.
- Fix building of COM servers (was broken in 1.0 because of the new build system).
- Mimic Python 2.4 behaviour with broken imports: sys.modules is cleaned up afterwise. This allows to package SQLObject applications under Windows with Python 2.4 and above.
- Add import hook for the following packages:
- PyOpenGL (tested 2.0.1.09)
- dsnpython (tested 1.3.4)
- KInterasDB (courtesy of Eugene Prigorodov)
- Fix packaging of code using “time.strptime” under Python 2.3+.
- (Linux) Ignore linux-gate.so while calculating dependencies (fix provided by Vikram Aggarwal).
- (Windows) With Python 2.4, setup UPX properly so to be able to compress binaries generated with Visual Studio .NET 2003 (such as most of the extensions). UPX 1.92+ is needed for this.
1.0 (2005-09-19) with respect to McMillan’s Python Installer 5b5
- Add support for Python 2.3 (fix packaging of codecs).
- Add support for Python 2.4 (under Windows, needed to recompiled the bootloader with a different compiler version).
- Fix support for Python 1.5.2, should be fully functional now (required to rewrite some parts of the string module for the bootloader).
- Fix a rare bug in extracting the dependencies of a DLL (bug in PE header parser).
- Fix packaging of PyQt programs (needed an import hook for a hidden import).
- Fix imports calculation for modules using the “from __init__ import” syntax.
- Fix a packaging bug when a module was being import both through binary dependency and direct import.
- Restyle documentation (now using docutils and reStructuredText).
- New Windows build system for automatic compilations of bootloader in all the required flavours (using Scons)
