导入python模块时如何解决KeyError? [英] How do I solve a KeyError when importing a python module?
问题描述
我试图从其他目录级别导入模块,所以我使用了:
I was trying to import a module from a different directory level so I used:
import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))
但是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,效果很好.
But now I get this error. I'm using Spyder and the first time I use the following import, it works fine.
from source.search.ci_search_project import CI_Search_Project
从第二次出现此错误.
文件"ipython-input-29-f35dfe634c32",模块中的第1行 runfile('C:/Users/nrshakya/Documents/CI/src/Comp_IntelPython/ci_search_project_test.py',wdir ='C:/Users/nrshakya/Documents/CI/src/Comp_IntelPython')

推荐答案
According to Vera's answer to their question, adding an empty __init__.py
file in the folder containing the module will fix this problem.
