title: No module named _sysconfigdata_nd
body: <p>This issue came up for me when I installed <a href="https://github.com/vim-scripts/Gundo" rel="nofollow noreferrer">Gundo</a> Vim plugin.</p>
  
  <p>I found many posts about <code>No module named _sysconfigdata_nd</code>, but all of them (<a href="https://stackoverflow.com/a/16224441/2640636">like this one</a>) refer to <a href="https://bugs.launchpad.net/ubuntu/+source/python2.7/+bug/1115466" rel="nofollow noreferrer">a bug in the Ubuntu package</a>, and suggest making a symbolic link like this:</p>
  
  <pre><code>sudo ln -s /usr/lib/python2.7/plat-*/_sysconfigdata_nd.py /usr/lib/python2.7/
  </code></pre>
  
  <p>This, however, is not applicable for me, as I'm using Python that I compiled myself.</p>
  
  <p>Per suggestion <a href="https://stackoverflow.com/a/20991008/2640636">here</a>, I did</p>
  
  <pre><code>sudo pip install --upgrade virtualenv
  </code></pre>
  
  <p>which created this directory</p>
  
  <pre><code>.../lib/python2.7/plat-linux2/
  </code></pre>
  
  <p>but there is no <code>_sysconfigdata_nd.py</code> in it.</p>
  
  <p>In my <code>.../lib/python2.7/</code> I have <code>_sysconfigdata.py</code> but no <code>_sysconfigdata_nd.py</code>.</p>
  
  <p>I've not been able to find any further leads.</p>
