ImportError: No module named 'pkg_resources.extern.six.moves'; 'pkg_resources.extern.six' is not a package
<p>I can not import pkg_resources. Whenever I tried it shows</p>

<p>Is <code>from pkg_resources</code> referring  to  <code>/usr/lib/python3.5/site-packages/pkg_resources/extern</code>  (in which there is no six package). Can you point out what I am doing wrong?</p>

<p>I am using Arch Linux,  Python 3.5.2</p>
