title: Installed module using pip, not found
body: <p>I am trying to install a package called "simpleguitk" via pip. (On Ubuntu 16.04 with Python 3.5)<br>
  After running </p>
  
  <pre><code>sudo -H pip3 install simpleguitk
  </code></pre>
  
  <p>it says installation is completed successfully. (Except for the pygame dependecy which is actually optional)</p>
  
  <pre><code>Collecting simpleguitk
  Using cached SimpleGUITk-1.1.3.tar.gz
  Collecting Pillow&gt;=2.0.0 (from simpleguitk)
  Using cached Pillow-3.4.2-cp35-cp35m-manylinux1_x86_64.whl
  Collecting pygame&gt;=1.9.0 (from simpleguitk)
  Could not find a version that satisfies the requirement pygame&gt;=1.9.0 (from simpleguitk) (from versions: 1.9.2.dev1, 1.9.2b7, 1.9.2b8)

  <p>I cannot find the package at /usr/local/lib/python3.5/dist-packages
  or /usr/lib/python3.5 or /usr/lib/python3</p>
  
  <p>When I try to import the module it says:</p>
  
  <pre><code>Traceback (most recent call last):
  File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  ImportError: No module named 'simpleguitk'
  </code></pre>
  
  <p>I tried to reinstall it, but running:</p>
  
  <pre><code>sudo -H pip3 uninstall simpleguitk
  </code></pre>
  
  <p>returns: "Cannot uninstall requirement simpleguitk, not installed
  "</p>
  
  <p>I have tried this on both pip 8.1.2 and pip 9.0.1 with the same results.
  I have even reinstalled Ubuntu, but still the same.</p>
  
  <p>I think Python Path is wrong as it does not have python 3.5 but I do not know how to fix it</p>
