title: ImportError: No module named bs4 because in wrong python folder
body: <p>I am new to Python. I am just trying to extract a string from an HTML file.
  I cannot make it work. Everyone is talking about Beautiful Soup but it doesn't work for me...</p>
  
  <p>This is my error:</p>
  
  <pre><code>ImportError: No module named bs4
  </code></pre>
  
  <p>I installed Beautiful Soup 4 already but I believe it is in the wrong folder:</p>
  
  <pre><code>sudo pip install beautifulsoup4
  Requirement already satisfied (use --upgrade to upgrade): beautifulsoup4 in /usr/local/lib/python2.7/dist-packages
  Cleaning up...
  </code></pre>
  
  <p>I am using Python 3.2. How do I force Beautiful Soup to install in the other folder?</p>
