[igraph] installing leidenalg package

[Paul Fishback]

Hello,

leidenalg is a package for community detection, which which implements an improved version of the classical Louvain method. ("From Louvain to Leiden: guaranteeing well-connected communities," Nature.com/scientificreports.com, March 2019. )

The package requires that igraph be installed, which I believe I have done correctly using the directions given at https://igraph.org/python/#pydoc1.

First I did it via pip install python-igraph

but I was also successful using

brew install igraph

To test it, I did the following:

import igraph as ig

G=ig.Graph.Erdos_Reny(100,.1)

This worked. However, despite repeated attempts, I was unable to install leidenalg. 

I've attached a text file showing the output I received. Is there any chance you can spot the source of my error and what I can do to fix it?

I'm using MAC OSX 10.14.6 Mojave and Python 3.7. 

Thanks

Paul Fishback
