ModuleNotFoundError: No module named pyjanitor despite pyjanitor being installed

I've confirmed the pyjanitor package is installed - it shows up in pip list and I get a confirmation if I try to reinstall with pip install pyjanitor. But then when I run import pyjanitor I get the error:

No module named 'pyjanitor'

What am I doing wrong?
