问题
I sat down tonight and have decided to leran how to use python. Inspired by this webpage scraping article. cam.ly/danesblog/2011/01/craigslist-arbitrage/
after working through a tutorial I:
1) downloaded and installed python: http://www.python.org/getit/ first 3.3 then 2.7
2) downloaded bs4: www.crummy.com/software/BeautifulSoup/bs4/download/
3) followed Brian Clapper's instructions: How can I install the Beautiful Soup module on the Mac?
- tried both easy_install and python setup.py install methods
I am still getting "ImportError: No module named bs4"
Python is installed in applications folder, the bs4 package auto installs in Library Is this the problem? I tried copying and moving the folder into Python application, but didn't work.
I have also tried both forms:
- from BeautifulSoup import BeautifulSoup
- from bs4 import BeautifulSoup
Thank you for the support.

The solution is in setting up the PATH the packages get installed. EPD or Canopy create their VirtualEnv set up in the .\~profile and .\~bash_profile files. These path may not be identical to the path pip install or easy_install try to install the packages. If you open bash_profile or profile files there should be a path similar to this :
VIRTUAL_ENV_DISABLE_PROMPT=1 source /Users/test_user/Library/Enthought/Canopy_64bit/User/bin/activate
I am using Enthought as my python editor so yours will be something else but what is important is if you are using pip or easy_install the address the python packages are installed should point here. Or put another way, your active virtual environment set up is in this address.
