找不到Python自定义模块，但已经存在 [英] Python custom module not found but already exists

问题描述

我创建了一个单独的文件来容纳我的Python文件的一些自定义问题类，并在执行以下命令后执行:coverage run test_syntax.py它会打印出以下错误，如

I have created a separate file to hold some custom issue classes for my Python file and upon execution of the following command: coverage run test_syntax.py it prints out the following error as seen in this Travis CI build:

Traceback (most recent call last):
  File "test_syntax.py", line 9, in 
    from ros import main as s
  File "/home/travis/build/Richienb/ROS-Code/src/ros/main.py", line 57, in 
    from errors import ConversionError, WrongInput, UnexpectedError
ModuleNotFoundError: No module named 'errors'

您可以在此处

此外，我已经进入src目录.

Also, I have already cd into the src directory.

推荐答案

您需要这样的相对导入(在我的计算机上需要第二次导入才能达到您发布的错误):

You need a relative import like this (second one was needed on my machine to even get to the error you have posted):

# in main.py
from .errors import ...
# ros.py
from . import errors
