title: Could not import runpy module
body: <p>I am trying to install a Python module on a raspberry pi that is running linux. 
  I am using Python 2.7.11 and have tried the following commands:</p>
  
  <p><code>python -m pip install schedule</code> </p>
  
  <p><code>python -m easy_install schedule</code></p>
  
  <p><code>python2.7 -m pip install schedule</code></p>
  
  <p>In each case I get the same error message:</p>
  
  <pre><code>Could not import runpy module
  </code></pre>
  
  <p>I get this same error message no matter what module I try to install. <strong>What could be causing this problem?</strong> I have been unable to find anything useful from Google searches I've done on the error message.</p>
  
  <p>EDIT: </p>
  
  <p>When  I try adding sudo to the command like either of these:</p>
  
  <p><code>sudo python -m pip install schedule</code> or <code>sudo /usr/bin/python -m pip install schedule</code></p>
  
  <p>I get the error:</p>
  
  <p><code>-sh: sudo: not found</code></p>
  
  <p>EDIT2:</p>
  
  <p>When I try <code>python -m pip install runpy</code> I still get:</p>
  
  <pre><code>Could not import runpy module
  </code></pre>
