pylint - pylint 和 git.exc 的奇怪错误

Question

给定以下 python 代码:

import git

try:
    raise git.exc.GitCommandError("dummy", "foo")
except git.exc.GitCommandError as exc:
    print(exc)

pylint 提示

************* Module test

代码工作正常，我不明白其中的错误。 git.exc 不是一个异常(exception)，而是一个模块:

> python3
Python 3.5.3 (default, Sep 27 2018, 17:25:39) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import git
>>> git.exc
<module 'git.exc' from '/tmp/tmp.ULCyvtUQWx/testenv/lib/python3.5/site-packages/GitPython-2.1.11-py3.5.egg/git/exc.py'>

pylint 版本是 2.3.1。我想知道这是否只是 pylint 中的一个错误，或者我是否遗漏了什么......

更新:由于某些原因，使用 git.GitCommandError 而不是 git.exc.GitCommandError 不会产生相同的错误。即使后者是类的原始名称。

尝试:from git.exc import GitCommandError 而不仅仅是 import git。
