python - 打开 Path 对象时 Pycharm 类型提示警告

Question

使用以下代码：

from pathlib import Path

file = Path("test.txt")

with open(file) as fl:
    pass 

Pycharm 给出以下警告file

Unexpected type(s): (Path) 

Possible types: 
  (Union[str, bytes, int]) 
  (Union[str, bytes, int, PathLike]) less... (Ctrl+F1) 

Inspection info: This inspection detects type errors in function call expressions. Due to dynamic dispatch and duck typing, this is possible in a limited but useful number of cases. Types of function parameters can be specified in docstrings or in Python 3 function annotations.

难道我做错了什么 ？
