title: Import of 'urllib3.util' failing in Python 2.7?
body: <p>I'm working on a Python script written by someone else. I'm trying to get it to run without any problems on my local development machine.</p>
  
  <p>I've installed the modules required by the script (requests, urllib3 and oath2), however I'm getting the following error which I'm struggling to resolve;</p>
  
  <pre><code>Traceback (most recent call last):

  </code></pre>
  
  <p>The scripts consist of three files; run.py, get_data.py and incr.py. The import statement in run.py is:</p>
  
  <pre><code>import get_data as gd, time
  </code></pre>
  
  <p>In get_data.py:</p>
  
  <pre><code>import sys, oauth2, requests, json
  </code></pre>
  
  <p>In incr.py:</p>
  
  <pre><code>import time
  </code></pre>
  
  <p>I assumed that I have to install a module named 'util'. I've searched for this module and cannot find it, therefore I think it seems like a deeper issue rather than just installing a module. </p>
  
  <p>I'd really appreciate it if anyone can point me in the right direction to resolve the issue.   I am using Python 2.7.3.</p>
