Installing and Using Setuptools
.. contents:: **Table of Contents**
The recommended way to bootstrap setuptools on any system is to download
`ez_setup.py`_ and run it using the target Python environment. Different
operating systems have different recommended techniques to accomplish this
basic routine, so below are some examples to get you started.
Setuptools requires Python 2.6 or later. To install setuptools
on Python 2.4 or Python 2.5, use the `bootstrap script for Setuptools 1.x
The link provided to ez_setup.py is a bookmark to bootstrap script for the
latest known stable release.

Windows 8 (Powershell)
For best results, uninstall previous versions FIRST (see `Uninstalling`_).
Using Windows 8 or later, it's possible to install with one simple Powershell
command. Start up Powershell and paste this command::
> (Invoke-WebRequest https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py).Content | python -
You must start the Powershell with Administrative privileges or you may choose
to install a user-local installation::
> (Invoke-WebRequest https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py).Content | python - --user
If you have Python 3.3 or later, you can use the ``py`` command to install to
different Python versions. For example, to install to Python 3.3 if you have
Python 2.7 installed::
> (Invoke-WebRequest https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py).Content | py -3 -
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.
Once installation is complete, you will find an ``easy_install`` 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. If you did a user-local install, the ``Scripts`` subdirectory is
Windows 7 (or graphical install)
For Windows 7 and earlier, download `ez_setup.py`_ using your favorite web
browser or other technique and "run" that file.
Most Linux distributions come with wget.
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::
> wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | sudo python
Alternatively, Setuptools may be installed to a user-local path::
> wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -O - | python - --user
Unix including Mac OS X (curl)
If your system has curl installed, follow the ``wget`` instructions but
replace ``wget`` with ``curl`` and ``-O`` with ``-o``. For example::
> curl https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py -o - | python
For more advanced installation options, such as installing to custom
locations or prefixes, download and extract the source
tarball from `Setuptools on PyPI <https://pypi.python.org/pypi/setuptools>`_
and run setup.py with any supported distutils and Setuptools options.
setuptools-x.x$ python setup.py install --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`_.

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.
.. _Bitbucket repo: https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
.. _0.6 branch: http://svn.python.org/projects/sandbox/branches/setuptools-0.6/#egg=setuptools-dev06
On Windows, if Setuptools was installed using an ``.exe`` or ``.msi``
installer, simply use the uninstall feature of "Add/Remove Programs" in the
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:
* `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
* 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!)
* Tarek Ziadé is the principal author of the Distribute fork, which
re-invigorated the community on the project, encouraged renewed innovation,
and addressed many defects.
* 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.
