di_i2c module missing ?

[rbuelund]

I have used this to install the GrovePi: curl -kL dexterindustries.com/update_grovepi | bash

But when i run a python script that contains: from grovepi import *

I get this error: ModuleNotFoundError: No module named 'di_i2c'

This is happening both on RPi 3 and 4 ??
