Python在Mac上找不到Pygame模块

Question

Using home-brew I have installed pygame as homebrew says this

"Requirement already satisfied: pygame in /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages (1.9.1release)"

but when I run idle3 and import pygame, python says this

">>> import pygame
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import pygame
ModuleNotFoundError: No module named 'pygame'"

Answer 1

Add /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages to your system path so Python knows to search here for libraries.

Here's a tutorial here

Answer 2

When running Idle3, you are likely not invoking your Python 2.7 interpreter for which you've installed pygame .

Does it work if you run python2.7 from the terminal and then import pygame there?
