Question

I am trying to install scipy in my vertualenv on mac.

Python using in virtualenv:

(Django)miki725mac:Django miki725$ python
Python 2.7.2 (default, Aug  3 2011, 00:58:00) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

I tries installing scipy by doing this which fails:

$ svn co http://svn.scipy.org/svn/scipy/trunk scipy
$ python setup.py build
$ python setup.py install

Then I tried:

$ pip install scipy

Also as per the suggestion I tried:

$ pip install -e git://github.com/scipy/scipy@effa6f68f8ada57b7986#egg=scipy-dev

Answer 1

Personally, I found the easiest and reliable way to install scipy/numpy on Mac OS Lion was through the scipy superpack shell-script on github . As Steve Jobs says - it just works. Nothing more to do.

Steps to install scipy in a virtual env:

• Download the scipy superpack install script
• Open the install script and change PYTHON=/usr/bin/python to PYTHON=`which python`
• Activate virtual env, and inside your virtual env, run the install script
• Bingo! that's all you need to do
