ImportError: cannot import name

Question

For some reason I receive an ImportError every time I try to import a class from another file. Here's the github page for my project: https://github.com/wheelebin/mcnextbot

Here's the error that I'm receiving:

Traceback (most recent call last):
  File "ircbot.py", line 36, in <module>
    from test import mcnextlvl
ImportError: cannot import name mcnextlvl

Answer 1

Here your from test import something refers to the module test in <PYTHONPATH>/lib , not yourselves test.py , and there is no submodule/class mcnextlvl there. You should use from lib.test import mcnextlvl as @sgmart commented.

Answer 2

__init__.py python文件允许您从lib包中导入名为'test'的各个模块。
