scipy install on mountain lion failing

Question

When I try to install scipy using pip install scipy it fails with the following traceback

Downloading/unpacking scipy
  Downloading scipy-0.10.1.tar.gz (6.2M         


        

Answer 1

This seems to be an issue with pip and numpy, which doesn't copy the compiled libraries into the site-packages directory.

You could install using pip into a virtualenv (which worked for me) or install from source using the

python setup.py install

method.

There are some comments about issue here:
