cairocffi is also necessary in environment.yaml

[wzrzt]

I built conda env by conda env create -f environment.yaml. But before pip install cairocffi, ig.plot() shows error: Type Error: ploting is not available.
So maybe cairocffi should be include in environment.yaml

    - cairocffi==1.2.0

The current setup should work (not I'm on Windows and weird things may happen on other platforms I haven't tested it).

Check out my answer to a related issue: #2 (comment)

Could you provide more details on your setup? OS, type of env you're using, etc.
