python-3.x - pytype 使用 attrs 默认工厂装饰器引发错误

Question

mypy没有错误，但pytype无法处理此代码并上升attribute-error。我该如何解决？

代码：

# foo/__init__.py
from typing import List

import attr


@attr.s(auto_attribs=True)
class A:
    x: List[int] = attr.ib()

    @x.default
    def bar(self) -> List[int]:
        return [1]

日志：

pytype foo

PS我想不# pytype: disable=attribute-error排队@x.default
