title: ImportError: No module named requests using two versions of python
body: <p>I've python 3.4.1 installed, and need to run python 2 script. I've installed python 2.7.5 by running <code>make install</code>. When i run my script it writes:</p>
  
  <pre><code>Traceback (most recent call last):
    File "/root/roseltorg/run.py", line 2, in &lt;module&gt;
      import requests
  ImportError: No module named requests
  </code></pre>
  
  <p>Then I'm trying to install requests module but:</p>
  
  <pre><code>pip install requests
  Requirement already satisfied (use --upgrade to upgrade): requests in /usr/local/lib/python3.4/site-packages/requests-2.11.1-py3.4.egg
  Cleaning up...
  </code></pre>
  
  <p>How to force install this module for python 2.7?</p>
