title: vim - Youcomplete me unable to find an appropriate Python library
body: <p>I have followed the instructions from here <a href="https://github.com/Valloric/YouCompleteMe">https://github.com/Valloric/YouCompleteMe</a>
  and have installed both:</p>
  
  <p>Cmake <code>sudo apt-get install build-essential cmake</code></p>
  
  <p>and Python Headers <code>sudo apt-get install python-dev python3-dev</code></p>
  
  <p>Then I <code>cd ~/.vim/bundle/YouCompleteMe</code> and runned: 
  <code>./install.py --clang-completer</code> I got:</p>
  
  <p><code>Searching Python 2.7 libraries...
  ERROR: unable to find an appropriate Python library.</code></p>
  
  <p>I then tried 
  <code>python3 install.py --clang-completer </code>
  but still got:</p>
  
  <p><code>Searching Python 3.4 libraries...
  ERROR: unable to find an appropriate Python library.</code></p>
  
  <p>Does anybody have an idea of what is going on?
  Thanks</p>
