Similar error - even after renaming the folder to 'agen' instead of 'autogen'

Traceback (most recent call last): File "/Users/GuestUser/GitHub/agen/app.py", line 1, in import autogen ModuleNotFoundError: No module named 'autogen'

EDIT: Even though I was on version 3.11.4 I had to switch it manually clicking on the version number in the bottom of VS Code as it was on 3.9

try this:
which python
copy & paste the link
<link_to_python> -m pip install pyautogen

this worked for me^
