Easily download, build, install, upgrade, and uninstall Python packages

Package Documentation

Latest Version: 3.4.4

Installing and Using Setuptools

Installation Instructions

Upgrading from Distribute

Currently, Distribute disallows installing Setuptools 0.7+ over Distribute. You must first uninstall any active version of Distribute first (see Uninstalling).

Upgrading from Setuptools 0.6

Upgrading from prior versions of Setuptools is supported. Initial reports good success in this regard.

Windows

The recommended way to install setuptools on Windows is to download ez_setup.py and run it. The script will download the appropriate .egg file and install it for you.

For best results, uninstall previous versions FIRST (see Uninstalling).

Once installation is complete, you will find an easy_install.exe program in your Python Scripts subdirectory. For simple invocation and best results, add this directory to your PATH environment variable, if it is not already present.

Unix-based Systems including Mac OS X

Download ez_setup.py and run it using the target Python version. The script will download the appropriate version and install it for you:

> wget https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py -O - | python

Note that you will may need to invoke the command with superuser privileges to install to the system Python.

Alternatively, on Python 2.6 and later, Setuptools may be installed to a user-local path:

> wget https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py
> python ez_setup.py --user

Advanced Installation

For more advanced installation options, such as installing to custom locations or prefixes, download and extract the source tarball from Setuptools on PyPI and run setup.py with any supported distutils and Setuptools options. For example:

setuptools-0.8$ python setup.py --prefix=/opt/setuptools

Use --help to get a full options list, but we recommend consulting the EasyInstall manual for detailed instructions, especially the section on custom installation locations.

Downloads

All setuptools downloads can be found at the project's home page in the Python Package Index. Scroll to the very bottom of the page to find the links.

In addition to the PyPI downloads, the development version of setuptools is available from the Bitbucket repo, and in-development versions of the 0.6 branch are available as well.

Uninstalling

On Windows, if Setuptools was installed using an .exe or .msi installer, simply use the uninstall feature of "Add/Remove Programs" in the Control Panel.

Otherwise, to uninstall Setuptools or Distribute, regardless of the Python version, delete all setuptools* and distribute* files and directories from your system's site-packages directory (and any other sys.path directories) FIRST.

If you are upgrading or otherwise plan to re-install Setuptools or Distribute, nothing further needs to be done. If you want to completely remove Setuptools, you may also want to remove the 'easy_install' and 'easy_install-x.x' scripts and associated executables installed to the Python scripts directory.

Using Setuptools and EasyInstall

Here are some of the available manuals, tutorials, and other resources for learning about Setuptools, Python Eggs, and EasyInstall:

Questions, comments, and bug reports should be directed to the distutils-sig mailing list. If you have written (or know of) any tutorials, documentation, plug-ins, or other resources for setuptools users, please let us know about them there, so this reference list can be updated. If you have working, tested patches to correct problems or add features, you may submit them to the setuptools bug tracker.

Credits

  • The original design for the .egg format and the pkg_resources API was co-created by Phillip Eby and Bob Ippolito. Bob also implemented the first version of pkg_resources, and supplied the OS X operating system version compatibility algorithm.
  • Ian Bicking implemented many early "creature comfort" features of easy_install, including support for downloading via Sourceforge and Subversion repositories. Ian's comments on the Web-SIG about WSGI application deployment also inspired the concept of "entry points" in eggs, and he has given talks at PyCon and elsewhere to inform and educate the community about eggs and setuptools.
  • Jim Fulton contributed time and effort to build automated tests of various aspects of easy_install, and supplied the doctests for the command-line .exe wrappers on Windows.
  • Phillip J. Eby is the principal author and maintainer of setuptools, and first proposed the idea of an importable binary distribution format for Python application plug-ins.
  • Significant parts of the implementation of setuptools were funded by the Open Source Applications Foundation, to provide a plug-in infrastructure for the Chandler PIM application. In addition, many OSAF staffers (such as Mike "Code Bear" Taylor) contributed their time and stress as guinea pigs for the use of eggs and setuptools, even before eggs were "cool". (Thanks, guys!)

CHANGES

0.8

  • Code base now runs on Python 2.4 - Python 3.3 without Python 2to3 conversion.

0.7.8

  • Distribute #375: Yet another fix for yet another regression.

0.7.7

  • Distribute #375: Repair AttributeError created in last release (redo).
  • Issue #30: Added test for get_cache_path.

0.7.6

  • Distribute #375: Repair AttributeError created in last release.

0.7.5

  • Issue #21: Restore Python 2.4 compatibility in test_easy_install.
  • Distribute #375: Merged additional warning from Distribute 0.6.46.
  • Now honor the environment variable SETUPTOOLS_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT in addition to the now deprecated DISTRIBUTE_DISABLE_VERSIONED_EASY_INSTALL_SCRIPT.

0.7.4

  • Issue #20: Fix comparison of parsed SVN version on Python 3.

0.7.3

  • Issue #1: Disable installation of Windows-specific files on non-Windows systems.
  • Use new sysconfig module with Python 2.7 or >=3.2.

0.7.2

  • Issue #14: Use markerlib when the parser module is not available.
  • Issue #10: ez_setup.py now uses HTTPS to download setuptools from PyPI.

0.7.1

  • Fix NameError (Issue #3) again - broken in bad merge.

0.7

  • Merged Setuptools and Distribute. See docs/merge.txt for details.

Added several features that were slated for setuptools 0.6c12:

  • Index URL now defaults to HTTPS.
  • Added experimental environment marker support. Now clients may designate a PEP-426 environment marker for "extra" dependencies. Setuptools uses this feature in setup.py for optional SSL and certificate validation support on older platforms. Based on Distutils-SIG discussions, the syntax is somewhat tentative. There should probably be a PEP with a firmer spec before the feature should be considered suitable for use.
  • Added support for SSL certificate validation when installing packages from an HTTPS service.

0.7b4

  • Issue #3: Fixed NameError in SSL support.

0.6.49

  • Move warning check in get_cache_path to follow the directory creation to avoid errors when the cache path does not yet exist. Fixes the error reported in #375.

0.6.48

  • Correct AttributeError in ResourceManager.get_cache_path introduced in 0.6.46 (redo).

0.6.47

  • Correct AttributeError in ResourceManager.get_cache_path introduced in 0.6.46.

  • Issue #375: Issue a warning if the PYTHON_EGG_CACHE or otherwise customized egg cache location specifies a directory that's group- or world-writable.

0.6.45

  • Issue #379: distribute_setup.py now traps VersionConflict as well, restoring ability to upgrade from an older setuptools version.

0.6.44

  • distribute_setup.py has been updated to allow Setuptools 0.7 to satisfy use_setuptools.

0.6.43

  • Issue #378: Restore support for Python 2.4 Syntax (regression in 0.6.42).

0.6.42

  • External links finder no longer yields duplicate links.
  • Issue #337: Moved site.py to setuptools/site-patch.py (graft of very old patch from setuptools trunk which inspired PR #31).

0.6.41

  • Issue #27: Use public api for loading resources from zip files rather than the private method _zip_directory_cache.
  • Added a new function easy_install.get_win_launcher which may be used by third-party libraries such as buildout to get a suitable script launcher.

0.6.40

  • Issue #376: brought back cli.exe and gui.exe that were deleted in the previous release.

0.6.39

  • Add support for console launchers on ARM platforms.
  • Fix possible issue in GUI launchers where the subsystem was not supplied to the linker.

0.6.35

Note this release is backward-incompatible with distribute 0.6.23-0.6.34 in how it parses version numbers.

  • Issue #278: Restored compatibility with distribute 0.6.22 and setuptools 0.6. Updated the documentation to match more closely with the version parsing as intended in setuptools 0.6.

  • Work around Jython bugs #1980 and #1981.

  • Issue #334: Provide workaround for packages that reference sys.__stdout__ such as numpy does. This change should address virtualenv #359 as long as the system encoding is UTF-8 or the IO encoding is specified in the environment, i.e.:

    PYTHONIOENCODING=utf8 pip install numpy
    
  • Fix for encoding issue when installing from Windows executable on Python 3.

  • Issue #323: Allow setup_requires requirements to supercede installed requirements. Added some new keyword arguments to existing pkg_resources methods. Also had to updated how __path__ is handled for namespace packages to ensure that when a new egg distribution containing a namespace package is placed on sys.path, the entries in __path__ are found in the same order they would have been in had that egg been on the path when pkg_resources was first imported.

0.6.30

  • Issue #328: Clean up temporary directories in distribute_setup.py.

  • Issue #283: Reenable scanning of *.pyc / *.pyo files on Python 3.3.
  • Issue #299: The develop command didn't work on Python 3, when using 2to3, as the egg link would go to the Python 2 source. Linking to the 2to3'd code in build/lib makes it work, although you will have to rebuild the module before testing it.
  • Issue #306: Even if 2to3 is used, we build in-place under Python 2.
  • Issue #307: Prints the full path when .svn/entries is broken.
