Re: [igraph] Solution for installing python-igraph for Anaconda using Homebrew igraph [OS X]

[Szabolcs Horvát]

Could this be a homebrew-induced problem?

I do not have homebrew, but I do have Anaconda and pip install python-igraph seems to work fine (it compiles everything and igraph can be used with no problems).

Great, thanks for the writeup! I'm thinking about incorporating this
somehow into the setup.py script, which already contains an Anaconda
Python specific hack - it all depends on whether there is a way for
setup.py to pass the --global-option flag "internally" to the
compiler.

I came across a few posts about possible solutions but wanted to offer an solution that does not involve renaming/moving system library files. The method below uses shell variables and extra pip flags to build python-igraph against the homebrew C library.
