Hi, python-igraph simply tries to import pycairo or cairocffi when it initializes the plotting module. If the import fails, it simply throws a "plotting not available" exception for all plotting attempts. So, to figure out what's wrong, try to import pycairo from the same Python session where you see this error -- this should give you a hint about what's wrong. Most likely pycairo is not installed correctly.
