title: PyCharm Python ImportError Behave
body: <p>I'm trying to run some tests in PyCharm using Behave and it keeps telling me I have this issue:</p>
  
  <pre><code>Traceback (most recent call last):
    File "/Library/Frameworks/Python.framework/Versions/2.7/bin/behave", line 7, in &lt;module&gt;
      from behave.__main__ import main
  ImportError: No module named behave.__main__
  </code></pre>
  
  <p>I had a colleague clone the project and they can run it fine on their machine, any insights? </p>
  
  <p>Python 2.7.10</p>
  
  <pre><code>$ pip freeze | grep ehave 
  behave==1.2.5
  </code></pre>
