title: cannot locate pip.pm for installing python modules
body: <p>I'm having trouble installing the <a href="https://pypi.python.org/pypi/regex" rel="nofollow noreferrer">regex</a> module for python, and would appreciate any suggestion and help. When I used "pip install" on a Windows system, the following error shows up:</p>
  
  <p>Can't locate pip.pm in @INC &lt;@INC contains: C:/Perl64/site/lib C:/Perl64/lib .) at C:\pathA\pathB\perl\bin/pip line 5. 
  BEGIN failed--compilation aborted at C:\pathA\pathB\perl\bin/pip line 5. </p>
  
  <p>All I did previously is to install pip, following this post: <a href="https://stackoverflow.com/questions/21222114/how-do-i-install-python-libraries">How do I install Python libraries?</a></p>
  
  <p>I succeeded in the following steps:</p>
  
  <pre><code>python ez_setup.py
  python get-pip.py
  </code></pre>
  
  <p>but not:</p>
  
  <pre><code>pip install setuptools --upgrade
  </code></pre>
  
  <p>that is when I got the errors.</p>
  
  <p>I am not familiar with using python on Windows, but I need to do it this time. Seems like there is another pip installed for perl on this computer, but when I check the environment variables, I can't really see anything about pip. </p>
  
  <p>For your information -- the python version is:
  2.7.7 |Anaconda 2.0.1 (64-bit)| (default, Jun 11 2014, 10:40:02) [MSC v.1500 64 bit (AMD64)]</p>
  
  <p>Thanks a lot in advance for your help!</p>
