问题描述
我已在pip3中安装了AppKit，但是从python3导入似乎无效。如何导入AppKit？
❯ pip3 install AppKit

❯ python3
Python 3.8.6 (default,Oct 8 2020,14:06:32)
[Clang 12.0.0 (clang-1200.0.32.2)] on darwin

>>> import AppKit
Traceback (most recent call last):
File "<stdin>",line 1,in <module>
ModuleNotFoundError: No module named 'AppKit'
>>>
这显示一个ModuleNotFoundError。是在另一个命名空间下吗？
解决方法
如果要使用AppKit，则必须安装PyObjC：
pip3 install -U PyObjC
