I am trying to install some package in cygwin's python, but I'm getting the following error: "easy_install: command not found".

I have tried to run "easy_install.py", the result is also "easy_install.py: command not found". I have tried to search the whole of cygwin's /usr tree for anything named with the prefix "easy", none found.

Am I missing something? AFAIK, easy_install tool should be batteries included in python 2.5. Or is there a package that needs to be installed for that that I missed?

From cygwin prompt, do:

$ wget http://peak.telecommunity.com/dist/ez_setup.py
$ python ez_setup.py

This will install easy_install on your cygwin.

Easy as py.

After installation, to use easy_install, make sure C:\Python27\Scripts (or similar) is in your PATH. –  Juuso Ohtonen Jun 2 '14 at 9:01

Easy Install is a python module (easy_install) bundled with setuptools, which can be found here: http://pypi.python.org/pypi/setuptools . You must install setuptools by yourself.

  • If you want to install it into windows python than use setuptools install script from cmd shell or use MS Windows installer
  • If you need python with setuptools to work within cygwin than:

    • use cygwin's own python (you can install one using cygwin's setup.exe)
    • use setuptools source

I don't think so. "which easy_setup" and "which easy_setup.py" says that it is not found. –  Alex Gontmakher May 11 '09 at 21:09
There is (at least now) a setuptools package in Cygwin which is almost certainly a better way to install it for a Cygwin installation - and easier for someone used to Cygwin. –  Francis Davey Jan 29 '14 at 20:42

easy_install is part of the setuptools package. This package is provided by cygwin. To install it, rerun the cygwin setup[...].exe installer, and at the package selection step, tick "Python/python-setuptools".

In addition to installing setuptools (as described in other answers), you also need to make sure C:\Python25\Scripts is in your PATH.

Are you sure? I use the python that comes with cygwin and not the separatly installed windows one. –  towi Feb 10 '13 at 15:32
