python - Anaconda not finding my packages installed with `pip`

Question

I'm new to Anaconda version of Python, and already I'm running into unpleasant problems.

I installed Anaconda per the instructions here, and it worked like charm, with all the included packages imported properly when demanded. Then I went on to install some extra packages which Anaconda did not included in the first place with pip:

$ sudo pip install BeautifulSoup mrjob pattern

The installations seems to be perfect, but when I try to import them in ipython, things get frustrating:

Python 2.7.6 |Anaconda 1.8.0 (64-bit)| (default, Nov 11 2013, 10:47:18) 
Type "copyright", "credits" or "license" for more information.

IPython 1.1.0 -- An enhanced Interactive Python.

Funny thing is, these packages can be very well imported when I'm not running the Anaconda bundle of python, after removing

# added by Anaconda 1.8.0 installer
export PATH="/home/username/anaconda/bin:$PATH"

from my .bashrc:

Python 2.7.5+ (default, Sep 19 2013, 13:48:49)

Did I miss anything during any of these installations that I ran? Should I manually link these packages to Anaconda so that it knows where to find them?

Answer 1

In the comments, it was determined that the pip in use was /usr/bin/pip; in other words, the system pip. The system pip will install into the system site-packages, not Anaconda's site-packages.

The solution is to make sure you're using Anaconda's pip when installing packages for use with Anaconda.
