How to install Scipy with pip on Mac Mountain Lion OS X v10.8

Question

I\'m having serious difficulty installing Scipy with pip on Mountain Lion. I\'ve tried:

sudo pip install -e git+https://github.com/scipy/scipy#egg=scipy-dev
         


        

Answer 1

On Mavericks the following works (might also work on other versions):

If you haven't already, install pip

sudo easy_install pip

Then install/update scipy

sudo pip install scipy -U

For some reason pip installs scipy to

/Library/Python/2.7/site-packages/

and does not remove the older version in

/System/Library/Frameworks/Python.framework/Versions/2.7//Extras/lib/python/scipy/

So just remove the old version and it works. Print the version number:

python -c "import scipy; print scipy.__version__"
