Never success to plotting graph by python igraph

Question

So many times after i type plot(g, layout=layout) poping out the error message:

I installed Cairo and py2cairo successfully as the doc said, but it didn't work.

I'm using mac os 10.8.x and I use ipython to try to plot as the tutorial.

Answer 1

First, make sure the python's real path by which python

Then, check the sys.path of current python.

I found that the brew install cairo is not installed in the python sys.path, so I have to add another PYTHONPATH:

export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages

to my .bashrc.
