Using Python with homebrew on OS X
I have been using Mac python for a while, and I decided to teach myself matplotlib
, because I want to have the experience with some common modules. I hear from everyone that once you get into non-standard modules, it's best to use python threw homebrew, so you have access to pip
and not easy_install
. After running: $brew install python --with-brewed-openssl
, $brew install python3 --with-brewed-openssl
, and $pip install matplotlib
, I go to the python shell with $python3
. Once there, I run import matplotlib.pyplot as plt
, and get the following:
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 00:54:21)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'matplotlib'
>>>
I have a feeling I'm still using the mac python, and not the brewed python, and I have tried editing the path, but it isn't working, even though I am running $source ~/.bash_profile
after every edit. Just in case I am editing the path wrong, I will post the file contents below:

Solution 1:
pip
usually installs modules for python2
if you have both python versions in your system, so for python3
you will probably need to use pip3
.
