Installing and Using Setuptools
Table of Contents
Currently, Distribute disallows installing Setuptools 0.7+ over Distribute. You must first uninstall any active version of Distribute first (see Uninstalling).
Upgrading from prior versions of Setuptools is supported. Initial reports good success in this regard.
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.
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/bootstrap/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/bootstrap/ez_setup.py > python ez_setup.py --user
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-x.x$ python setup.py --prefix=/opt/setuptools
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.
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.
Here are some of the available manuals, tutorials, and other resources for learning about Setuptools, Python Eggs, and EasyInstall:
- The EasyInstall user's guide and reference manual
- The setuptools Developer's Guide
- The pkg_resources API reference
- Package Compatibility Notes (user-maintained)
- The Internal Structure of Python Eggs
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.
- 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 seminal author 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!)
- Since the merge with Distribute, Jason R. Coombs is the maintainer of setuptools. The project is maintained in coordination with the Python Packaging Authority (PyPA) and the larger Python community.
