I did

pip3 install graphlib

I can now import graphlib, but

from graphlib import TopologicalSorter

fails. If I import graphlib, it tells me that there is no attibute TopologicalSorter.

What am I doing wrong?

importerror python

Confusingly, graphlib on PyPI is not the real graphlib, so you don’t have the right package installed.

You need to replace graphlib’s evil twin with the real thing:

pip3 uninstall graphlib
pip3 install graphlib-backport
