problem in installing pypol
Question: I have been trying to install pypol in cygwin. But when I do setup where I
have to type python setup.py install then it displays an error as the
following:

Traceback (most recent call last):

File "setup.py", line 1, in

    
    
    from setuptools import find_packages, setup, Command
    

File "/cygdrive/c/pypol_-0.4/setuptools/**init**.py", line 2, in

    
    
    from setuptools.extension import Extension, Library

    from setuptools.dist import _get_unpatched

    from setuptools.command.install import install

in

    
    
    from pkg_resources import Distribution, PathMetadata, ensure_directory
    

ImportError: No module named pkg_resourceserror

Its clear that some of the modules are missing in my setuptools but I
installed the setuptools again and they are still not there. How do I get out
of this problem? Please help. Thank you.


Answer: [What is causing ImportError: No module named pkg_resources after upgrade of
Python on os X?](http://stackoverflow.com/questions/1756721/what-is-causing-
importerror-no-module-named-pkg-resources-after-upgrade-of-pytho)

is informative. It suggests that you're invoking the wrong version of
`python`. Do you already have `python` installed under Windows?

If you **do** have another version of Python (you can probably check under
cygwin with `which python`) make sure that you're invoking the right one,
which is most easily done by putting its binary path at the beginning of your
`PATH` environmental variable in your `~/.bashrc` or similar.

Then, re-install `setuptools` with the correct python, and everything should
go smoothly.

Really, the linked answer tells you all you need to know, except it's talking
about multiple versions on OSX rather than Windows.
