title: pip can't install package because it can't find swig2.0 binary
body: <p>I'm using python 2.7.9 (64 bit) with pip 1.5.6 and virtualenv 12.1.1 on Windows 7 powershell. I created a virtual environment named <em>NeuralNetwork</em> and I'm trying to install the package fann2 1.0.7:</p>
  
  <pre><code>PS C:\Python27\envs\NeuralNetwork\Scripts&gt; pip.exe install fann2
  Collecting fann2
  (...)
  Exception: Couldn't find swig2.0 binary!
  </code></pre>
  
  <p>I guess I have to install this <code>swig2.0 binary</code> for Windows 7, but I can't figure out how exacly. I went to <a href="http://www.swig.org/download.html" rel="nofollow">a swig site I found on Google</a> and downloaded swigwin 2.0.12. The zip file came with a pre-compiled <code>swig.exe</code>. I read the documentation for Windows, but I didn't understand where should I put this file nor how to proceed afterward. I'm new to python and I've never heard of swig before. Could someone please help me?</p>
