python feedparser ImportError: No module named feedparser
I receive an error when I attempt to include the feedparser library into the interactive Python environment:
>>>> import feedparser
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named feedparser
This also happens with BeautifulSoup and pydelicious. Why am I getting this error?
Using OS X 10.8.3, which include the following files in the /usr/bin directory:
$ ll python*

Python's location:
$ which python
/usr/bin/python
Python's version:
$ python -V
Python 2.7.2
It was probably unnecessary, but I installed Python with Homebrew:
$ brew install python
Which installed these files:
$ brew list python

Then I installed feedparser:
$ pip install feedparser
Which resulted in these files:
$ ll /usr/local/lib/python2.7/site-packages/f*
-rw-r--r-- 1 foobar admin 166583 Apr 24 20:16 /usr/local/lib/python2.7/site-packages/feedparser.py
-rw-r--r-- 1 foobar admin 138040 Apr 24 20:16 /usr/local/lib/python2.7/site-packages/feedparser.pyc
I was hoping to avoid these sorts of problems by using Homebrew (which has worked well with other libraries). What am I missing?
Answer
If your Python is at /usr/bin/python, then you are not using the Homebrew-built Python, but the OS X default one. (Also note the version number discrepancies in your output.) So any package that you install with pip will be installed into the Homebrew space, but will not be visible to the OS X-supplied Python installation. (OS X does not supply pip, so that's quite like the Homebrew one.)
The fix for you is quite likely to update your path to have /usr/local/bin come before /usr/bin.
