[Python] Can't import moviepy.editor

i was trying to create an application with python using the moviepy library. I installed it using:

pip install moviepy


I found this from a MoviePy crash-course:

# Import everything needed to edit video clips
from moviepy.editor import *


After trying to run this line i get this error:
