title: pyenv python2 version not working
body: <p>I am seeing this in my terminal:</p>
  
  <pre><code>gyp ERR! stack pyenv: python2: command not found
  gyp ERR! stack 
  gyp ERR! stack The `python2' command exists in these Python versions:
  gyp ERR! stack   2.7.5
  gyp ERR! stack   2.7.8
  </code></pre>
  
  <p>I am super confused what this means. How can I configure <code>pyenv</code> so that this works?</p>
  
  <p>I am looking to do this:</p>
  
  <pre><code>python =&gt; version 2.7
  python2 =&gt; version 2.7
  python3 =&gt; version 3.6.4
  </code></pre>
  
  <p>python3 is configured fine, but python/python2 are not and I can't figure out why.</p>
