title: Python can't find installed modules
body: <p>I've used these modules before, even in a Python script inside a folder where I have other working scripts. Here's my imports:</p>
  
  <pre><code>import os
  import sys    
  import urllib.request as urllib, simplejson as json, requests
  import subprocess
  import Popen, PIPE
  import time
  </code></pre>
  
  <p>I get this in my console:</p>
  
  <pre><code>Traceback (most recent call last):
    File "party.py", line 4, in &lt;module&gt;
      import urllib.request as urllib, simplejson as json, requests
  ImportError: No module named request
  </code></pre>
  
  <p>How come? I've tried </p>
  
  <pre><code>sudo pip install request
  </code></pre>
  
  <p>..but with no luck. What is causing this?</p>
