after pip successful installed: ModuleNotFoundError

Question

I am trying to install the SimPy module so that I can use it in IDLE. However, everytime I try to import in IDLE, I got an error. I already tried reinstalling Python and Pip

Answer 1

When this happened to me (on macOS), the problem turned out to be that the python installation I specified at the top of my script.py was not the same python installation that conda/pip were using on the command line.

To get the command line and my script to match up, I changed the header in my script.py to just use:

#!python

Then when I ran ./script.py on the command line, everything finally worked.
