ModuleNotFoundError: No module named'firebase_admin'

When I imported firebase_admin to link with the firebase database in python, ModuleNotFoundError: No module named'firebase_admin'was returned. Since it is installed with pip3, I checked with pip list and found that firebase_admin is installed, and even if I check the save location with $pip show firebase_admin and check the import route with sys, I can confirm that the path is in place. I did. I can't find a solution, but please teach me if you understand.
