ImportError - Module Not Found?

Question

My directory structure is:

project_folder/
..my_project/
....server/
......server.py
......api.py

When I'm in the project_folder and run python3 my_project/server/server.py , I get ModuleNotFoundError: No module named 'my_project' with the line of code:

from my_project.server.api import app as application

Weirdly, when I run my tests with Pytest everything passes. I've been trying to solve my problem without using this code snippet, which I always see recommended to solve these problems:

import sys
from os import path
sys.path.append( path.dirname( path.dirname( path.abspath(__file__) ) ) )

Any tips?

Answer 1

您尝试调用的模块已经在同一个程序包中，因此只需执行

from api import app as application

Answer 2

在my_project和服务器文件夹中添加一个空的__init__.py文件。

Answer 3

run this cd my_project/server/ and then python server.py
Or remove this line from server.py import my_project

And if you are trying to make a module add

__init__.py

to your server dir
