title: PyCharm doesn't recognize installed module
body: <p>I'm having trouble with using 'requests' module on my Mac. I use python34 and I installed 'requests' module via pip. I can verify this via running installation again and it'll show me that module is already installed.</p>
  
  <pre><code>15:49:29|mymac [~]:pip install requests
  Requirement already satisfied (use --upgrade to upgrade): requests in /opt/local/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages
  </code></pre>
  
  <p>Although I can import 'requests' module via interactive Python interpreter, trying to execute 'import requests' in PyCharm yields error 'No module named requests'. I checked my PyCharm Python interpreter settings and (I believe) it's set to same python34 as used in my environment. However, I can't see 'requests' module listed in PyCharm either. </p>

  <p>It's obvious that I'm missing something here. Can you guys advise where should I look or what should I fix in order to get this module working? I was living under impression that when I install module via pip in my environment, PyCharm will detect these changes. However, it seems something is broken on my side ...</p>
