您需要更新您的 sys.path，这是python查找模块的地方，而不是你当前环境中的系统路径，这就是os.environ["PATH"] 指的是.

You need to update your sys.path, which is where python looks for modules, as opposed to your system's path in the current environment, which is what os.environ["PATH"] is referring to.

示例:

import os, sys
sys.path.insert(0, os.path.abspath(".."))
import aa

这样做之后，你可以像这样在 aa 中使用你的函数:aa.myfunc()

After doing this, you can use your functions in aa like this: aa.myfunc()
