title: Python-Failure to import BeautifulSoup4 in Python3.3.1, but success in Python 2.7-Installed using easy_install
body: <p><strong>Background &amp; What I did:</strong> I'm writing a webpage content extractor, and realized the need to install BeautifulSoup4 to better parse my HTML file. On my Ubuntu 13.04 machine, I have both Python2.7(system default) and Python3.3.1 installed. After a few failures with both <code>pip</code> and <code>easy_install</code> due to the "SSL certificate" issue, I got to finally install BeautifulSoup4 using easy_install on my last try. </p>
  
  <p><strong>But:</strong> It seems that <code>easy_install</code> installed BS4 into the Python2.7 directory(<code>/usr/local/lib/python2.7/dist-packages</code>) in my system, as you can tell from the information below: </p>
  
  <pre><code>Searching for beautifulsoup4

  Installed /usr/local/lib/python2.7/dist-packages/beautifulsoup4-4.2.1-py2.7.egg 
  </code></pre>
  
  <p>Right now I'm able to import BS4 in Python2.7, but not in Python3.3, with this error message: </p>
  
  <pre><code>&gt;&gt;&gt; import bs4
  Traceback (most recent call last):
    File "&lt;pyshell#8&gt;", line 1, in &lt;module&gt;
      import bs4
  ImportError: No module named 'bs4'  
  </code></pre>
  
  <p><strong>Question:</strong> Should I add this Python2.7 directory to my Python3.3 library directory? (I worry about future conflict of different versions of a same module due to this shared library path) or should I uninstall BS4 and try it again with <code>pip</code> so maybe it'll install BS4 in Python3.3 directory? (right now this got returned when I try to install BS4 again using <code>pip</code>: <code>Requirement already satisfied (use --upgrade to upgrade): beautifulsoup4 in ./beautifulsoup4-4.2.1-py2.7.egg</code>) Other general pointers about solving this problem will also be appreciated. Thank you!  </p>
