super() argument 1 must be type, not classobj

When trying to scrape a wiki, I get the following error:

What version of mwclient do you have? How did you install it?

[BotJohn]

0.11, installed via pip.

Same error, any help?

[Anonymous3-a]

Ok, try this: run pip --force-reinstall "mwclient==0.10". It's not giving the error now, it seems like it's working?

Faced same issue.
The below solved.
pip install "mwclient==0.10"

The --force-reinstall command just returns an error, but the install command @agnelvishal replied with works.
