Question

I am trying to install numpy on my mac machine.
Whatever I try, I end up getting this error when trying to run my python code

 import numpy as np
File "/Library/Python/2.6/site-packages/numpy-2.0.0.dev_26aa3cf_20110808-py2.7-macosx-

Also when I enter Python in my terminal it takes me to python 2.6.1 version.
How do I solve this?

Answer 1

I would recommend using macports or fink as a package system.

With macports, installing numpy is as easy as

cd /opt/local/bin 
sudo ./port install py27-numpy

where py27 may be replaced with your favorite python version.
