title: pip not installing modules
body: <p>As per object. I'm running Python 2.7.10 under Windows 7 64 bit. I added C:\Python27\Scripts to my PATH, and I can run <code>pip</code>, but it's not able to install modules. For example</p>
  <pre class="lang-none prettyprint-override"><code>pip install numpy
  </code></pre>
  <p>gives</p>
  <pre class="lang-none prettyprint-override"><code>Collecting numpy
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after
  connection broken by 'ProtocolError('Connection aborted.', gaierror(11004,'getaddrinfo failed'))': /simple/numpy/
  </code></pre>
  <p>It keeps retrying and failing for a while, and then it exits with</p>
  <pre class="lang-none prettyprint-override"><code>Could not find a version that satisfies the requirement numpy (from versions:
  )
  No matching distribution found for numpy
  </code></pre>
  <p>Probably I'm behind a firewall, but I'm quite disappointed because I can install packages under <a href="https://en.wikipedia.org/wiki/R_%28programming_language%29" rel="nofollow noreferrer">R</a> perfectly fine with <code>install.packages</code>, and I don't see why I can't do the same with Python. If I install packages manually (in the case of NumPy, from here</p>
  <p><a href="https://pypi.python.org/pypi/numpy/1.10.1" rel="nofollow noreferrer">NumPy</a></p>
  <p>what do I miss, with respect to using <code>pip</code>?</p>
  <p>As per suggestions in the comments, I downloaded the .whl file for NumPy from <a href="https://pypi.python.org/pypi/numpy/1.10.1" rel="nofollow noreferrer">NumPy</a>. I navigated to the downloads dir and executed</p>
  <pre class="lang-none prettyprint-override"><code>pip install numpy-1.10.1-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl
  </code></pre>
  <p>I only got</p>
  <pre class="lang-none prettyprint-override"><code>numpy-1.10.1-cp27-none-macosx_10_6_intel.macosx_10_9_intel.macosx_10_9_x86_64.macosx_10_10_intel.macosx_10_10_x86_64.whl is not a supported wheel on this platform.
  </code></pre>
  <p>What should I do?</p>
