title: ImportError: No Module named six; six already installed
body: <p>I'm running python 3.6 on Mac OS X El Capitan.</p>
  <p>I'm trying to run code that uses the six module, but am getting the following error:</p>
  <p><code>ImportError: No module named six</code>.</p>
  <p>When I search for six it appears no problem, and I've made sure that the location is included in the sys.path</p>
  <pre><code>$ pip show six
  Name: six
  Version: 1.10.0
  Summary: Python 2 and 3 compatibility utilities

  </code></pre>
  <p>However, when I try to run something basic I encounter an error:</p>
  <pre><code>$ python -c &quot;import six; print (six.__version__)&quot;
  Traceback (most recent call last):
    File &quot;&lt;string&gt;&quot;, line 1, in &lt;module&gt;
  AttributeError: module 'six' has no attribute 'version'
  </code></pre>
  <p>I've tried uninstalling and reinstalling, and have tried installing using <code>$ python -m pip install six</code>, but nothing has worked.</p>
  <p>If anyone has any ideas or needs more information, I would appreciate it.</p>
