title: Invalid Python SDK Error while using python 3.4 on PyCharm
body: <p>When I switch my PyCharm to use Python 3.4.3 I am getting the error:</p>
  
  <blockquote>
    <p>Invalid Python SDK</p>
  </blockquote>
  
  <p>Also PyCharm does not automatically find the Python 3.4 interpreter for me, even though it is on desired path <code>/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4</code>.</p>
  
  <p>See screenshot:</p>

  <p>Although the interpreter does work.
  I am able to get correct output as expected, but code completion related to python 3.4 is not working.</p>
  
  <p>e.g. <code>print("hello world!)</code> still shows an error on the editor, but the console shows the correct output.</p>
