As a test that I had installed things correctly, I ran the example program here: https://github.com/p5py/p5

The program runs exactly as shown in the gif, but:

  • Keywords related to the mouse are underlined and described as having an unresolved reference. Importing the reference is not offered as an option.
    -Lots of errors are generated when I run the code.
    I'm using:
  • PyCharm 2021.3.2 Community edition on Windows 10 as my editor
  • python 3.10.4
  • p5 0.7.1
  • I also tried running the code in IDLE 3.10.4.

See below for code and error messages from PyCharm and IDLE below.
Thank you!

======= Code =========
(as copied form github)
from p5 import *

def setup():
size(640, 360)
no_stroke()
background(204)

def draw():
if mouse_is_pressed:
fill(random_uniform(255), random_uniform(127), random_uniform(51), 127)
else:
fill(255, 15)

circle_size = random_uniform(low=10, high=80)

circle((mouse_x, mouse_y), circle_size)

def key_pressed(event):
background(204)

run()
