在Mac上安装python igraph anaconda

Question

I decided to uninstall and reinstall igraph package for anaconda on my mac. I started running into some issues - I've looked at all the links and have tried the following...

brew install pkg-config --> already installed
brew install igraph --> installed and linked

but since I'm using anaconda, I can't use the brew installed version of igraph (please correct me if this is not the case)

when I run...

pip install python-igraph

I get the following output

Answer 1

This is a version mismatch between the version of the C core of igraph that you have on your machine (0.6.5) and the version of the Python interface that you are trying to compile (0.7.1-4). You need to:

brew uninstall igraph
brew update
brew install igraph

This will install igraph 0.7.1 (verify it with brew info igraph after compilation) and then you are good to go with pip install python-igraph .
