开发一个新的包并获取ModuleNotFoundError：没有命名的模块

Question

I was writing a little application where I wanted to create a module containg a small group of classes, but when I try to import the classes from the main application, I get the error:

 my_project python3 main.py 
1
Traceback (most recent call last):
  File "main.py", line 2, in <module>
    import receivers
  File "/home/mario/Documents/python/my_project/receivers/__init__.py", line 2, in <module>
    from icinga import Icinga
ModuleNotFoundError: No module named 'icinga'

The file in the project are:

├── main.py
└── receivers
    ├── icinga.py
    ├── __init__.py

where main.py

#!/usr/bin/env python
import receivers

icinga = receivers.icinga.Icinga()

the file receivers/icinga.py

class Icinga:

    def __init__(self):
        print("I'm Icinga!")

the file receivers/__init__.py

print('1')
from icinga import Icinga
print('2')

Can someone please tell me what I do wrong?

Thanks in advance

Answer 1

If you just want to import the Icinga class, you can do it as

from receivers.icinga import Icinga

If you want to call the import statement on receivers, you should alter the init .py, on 2nd line, to:

from .icinga import Icinga

I reproduced your problem here, and was able to solve it like that.

Edit:

Doing this second thing (on __init__.py), you would be able to call it on the main.py as:

import receivers
receivers.icinga.Icinga()
