UPM Module problem

Hi! I tried to use LCD from grove. When I used simple example of code, I got this error: ModuleNotFoundError: No module named 'upm'. Before, when I tried to install it, could'nt do it. Please help

Well an exact error message of why you couldn't do it would help

But I have a feeling this will help https://discord.com/channels/818384379197784084/1217798894985941072
