Background & What I did: 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 pip and easy_install due to the "SSL certificate" issue, I got to finally install BeautifulSoup4 using easy_install on my last try.
But: It seems that easy_install installed BS4 into the Python2.7 directory(/usr/local/lib/python2.7/dist-packages) in my system, as you can tell from the information below:

Adding beautifulsoup4 4.2.1 to easy-install.pth file
Installed /usr/local/lib/python2.7/dist-packages/beautifulsoup4-4.2.1-py2.7.egg
Right now I'm able to import BS4 in Python2.7, but not in Python3.3, with this error message:
>>> import bs4
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
import bs4
ImportError: No module named 'bs4'
Question: 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 pip so maybe it'll install BS4 in Python3.3 directory? (right now this got returned when I try to install BS4 again using pip: Requirement already satisfied (use --upgrade to upgrade): beautifulsoup4 in ./beautifulsoup4-4.2.1-py2.7.egg) Other general pointers about solving this problem will also be appreciated. Thank you!
According to the section Download Beautiful Soup on the official homepage, you can install the python-beautifulsoup4 package on Ubuntu 13.04.
Try this to prevent the conflict between Python 2.7 and 3.3. Before you do that though, I'd recommend removing the Beautiful Soup egg to avoid a potential version conflict.
