类不能使用 mypy 子类化“QObject"(类型为“Any") [英] Class cannot subclass 'QObject' (has type 'Any') using mypy

问题描述

我有一个继承 QObject 的类.一切正常，但是当我在其上运行 mypy 时出现错误:

I have a class that subclasses QObject. Everyting works fine but when I run mypy on it I get the error:

"error: Class cannot subclass 'QObject' (has type 'Any')" 

此刻我完全被困住了.我一直在阅读 mypy 文档，但找不到错误所在.

At the moment I am totally stuck. I Have been reading the mypy docs but couldn't find where the error was.

代码如下:

from PyQt5.QtCore import QObject

class ServiceLocator(QObject):

    def __init__(self) -> None:
        super().__init__()
        ...

干杯.

推荐答案

当 mypy 没有类的类型信息(在您的情况下是由于缺少存根)并且您有 --disallow-subclassing-any 打开.您可以禁用此标志，添加输入信息，或者，如您所指出的，放置 # type: ignore 以消除错误.

This error occurs when mypy doesn't have type information for a class (in your case due to a lack of stubs) and you have --disallow-subclassing-any turned on. You can either disable this flag, add typing information, or, as you pointed out, put a # type: ignore to silence the error.
