ERROR with grove_rgb_lcd

When I’m running the program Home_Weather_Display I get the following errors:

Traceback (most recent call last):
File “Home_Weather_Display.py”, line 41, in
from grove_rgb_lcd import *
ImportError: No module named grove_rgb_lcd

I have already used the command: sudo curl -kL dexterindustries.com/update_grovepi

It doesn’t seem to do the trick
