python - 导入 python 模块时如何解决 KeyError？

Question

我试图从不同的目录级别导入模块，所以我使用了:

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

但现在我得到了这个错误。我正在使用 Spyder，并且第一次使用以下导入时，它工作正常。

from source.search.ci_search_project import CI_Search_Project

从第二次我得到这个错误。

According to Vera's answer to their question , 添加一个空的 __init__.py包含模块的文件夹中的文件将解决此问题。
