I’m doing the following:
> brew link homebrew/science/igraph > pip install python-igraph The brew step appears to work fine, but the pip step doesn’t work (with or without ‘sudo); nor does easy_install. My version of Python is: Python 2.7.9 |Anaconda 2.1.0 (x86_64)| I have a 3MB pip.log; here are some excerpts: /Users/areich/anaconda/bin/pip run on Fri Mar 6 11:30:16 2015 Downloading/unpacking python-igraph Getting page https://pypi.python.org/simple/python-igraph/ URLs to search for versions for python-igraph: * https://pypi.python.org/simple/python-igraph/ Analyzing links from page https://pypi.python.org/simple/python-igraph/ Skipping link https://pypi.python.org/packages/2.4/p/python-igraph/python-igraph-0.5.1.win32-py2.4.exe#md5=aa4d24dbcf599f28fa146d20c4267897 (from https://pypi.python.org/simple/python-igraph/); unknown archive format: .exe . . .
