Question

I need to install Numpy on my Mac OS X Lion 10.7. I googled a little bit, it seems like there are a lot of stuff needs to be installed. And some says I need install Xcode be

Answer 1

Based on this post, I found that Chris Fonnesbeck keeps a highly functional installer script for OSX 10.7 at the OSX SuperPack Github site.

Because I hapened to have all the dependencies (such as gfortran) already, I did not use his full shell script. Rather I just did

git clone --depth=1 git://github.com/fonnesbeck/ScipySuperpack.git  
python -m easy_install -N -Z ScipySuperpack/*.egg   

And it worked beautifully. In particular, it worked better than the .dmg files from the official numpy and scipy distributions, and better than pip install.

Answer 2

You can install numpy/scipy using pip, If pip is not installed on your machine, you can install it with easy_install:

sudo easy_install pip

Then install numpy:

sudo pip install numpy

Answer 3

The easiest way that I found was to visit http://sourceforge.net/projects/numpy/files/NumPy/, pick the folder of the latest version, and then download the .dmg file that matched my installed version of Python.
