Installation Instructions
|
|
-------------------------
|
|
|
|
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
|
|
<https://raw.githubusercontent.com/pypa/setuptools/bootstrap-py24/ez_setup.py>`_.
|
|
|
|
The link provided to ez_setup.py is a bookmark to bootstrap script for the
|
|
latest known stable release.

|
|

|
|
|
|
Windows (Powershell 3 or later)
|
|
===============================
|
|
|
|
For best results, uninstall previous versions FIRST (see `Uninstalling`_).
|
|
|
|
Using Windows 8 (which includes PowerShell 3) or earlier versions of Windows
|
|
with PowerShell 3 installed, it's possible to install with one simple
|
|
Powershell command. Start up Powershell and paste this command::
|
|
|
|
> (Invoke-WebRequest https://bootstrap.pypa.io/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://bootstrap.pypa.io/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://bootstrap.pypa.io/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
|
|
distribution 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
|
|
``$env:APPDATA\Python\Scripts``.
|
|
|
|
|
|
Windows (simplified)
|
|
====================
|
|
|
|
For Windows without PowerShell 3 or for installation without a command-line,
|
|
download `ez_setup.py`_ using your preferred web browser or other technique
|
|
and "run" that file.
|
|
|
|
|
|
Unix (wget)
|
|
===========
|
|
|
|
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://bootstrap.pypa.io/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://bootstrap.pypa.io/ez_setup.py -O - | sudo python
|
|
|
|
Alternatively, Setuptools may be installed to a user-local path::
|
|
|
|
> wget https://bootstrap.pypa.io/ez_setup.py -O - | python - --user
|
|
|
|
Note that on some older systems (noted on Debian 6 and CentOS 5 installations),
|
|
`wget` may refuse to download `ez_setup.py`, complaining that the certificate common name `*.c.ssl.fastly.net`
|
|
does not match the host name `bootstrap.pypa.io`. In addition, the `ez_setup.py` script may then encounter similar problems using
|
|
`wget` internally to download `setuptools-x.y.zip`, complaining that the certificate common name of `www.python.org` does not match the
|
|
host name `pypi.python.org`. Those are known issues, related to a bug in the older versions of `wget`
|
|
(see `Issue 59 <https://bitbucket.org/pypa/pypi/issue/59#comment-5881915>`_). If you happen to encounter them,
|
|
install Setuptools as follows::
|
|
|
|
> wget --no-check-certificate https://bootstrap.pypa.io/ez_setup.py
|
|
> python ez_setup.py --insecure
|
|
|
|
|
|
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://bootstrap.pypa.io/ez_setup.py -o - | python
|
|
|
|
|
|
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 <https://pypi.python.org/pypi/setuptools>`_
|
|
and run setup.py with any supported distutils and Setuptools options.
|
|
For example::
|
|
|
|
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`_.
|
|
|
|
.. _EasyInstall manual: https://pythonhosted.org/setuptools/EasyInstall
|
|
.. _the section on custom installation locations: https://pythonhosted.org/setuptools/EasyInstall#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.
|
|
|
|
.. _the project's home page in the Python Package Index: https://pypi.python.org/pypi/setuptools
|
|
|
|
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
|
|
|
|
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.

|
|
|
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!)
|
|
|
|
* 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.
