python 3.7 import smbus ModuleNotFoundError no module named 'smbus'
I successfully built python 3.7 on my raspberry pi zero. now when I run my program using:
python3 DungeonCube.py
I get the following error:
import smbus
ModuleFoundError: No module named 'smbus'
I have searched for solutions and it seems no one has gotten this far with python 3.7 on a raspberry pi. other guides say to reinstall smbus or install smbus2 and that does not work.
dpkg-query -L python3-smbus shows:

Any ideas how to get this working?

Answer
The python3-smbus library which is installed on your system seems a little old. It works for Python 3.5 but not for Python 3.7.
You have two solutions:
- downgrade your Python to use Python 3.5
- choose another library: you can try smbus2 which is more uptodate.
