title: neovim can not find python correctly because of virtualenv or conda?
body: <p>I install <code>YouCompleteMe</code> and <code>UltiSnips</code> plugins in my <code>neovim</code>. Normally, everything is ok. </p>
  
  <p>But I am using <a href="http://conda.pydata.org/docs/intro.html" rel="noreferrer"><code>MiniConda</code></a> in my python developing, <code>MiniConda</code> is something like <code>virtualenv</code>, I have a virtual python env called <code>parser</code>, when I activate this virtualenv with <code>source activate parser</code>, something is wrong:</p>
  
  <pre><code>YouCompleteMe unavailable: requires Vim compiled with Python 2.x support
  UltiSnips requires py &gt;= 2.7 or py3
  Press ENTER or type command to continue
  </code></pre>
  
  <p>so the problem is <code>neovim</code> can not find python properly, I am confused why <code>virtualenv</code> affect <code>neovim</code>?</p>
