python - 使用 pathlib 时，出现错误 : TypeError: invalid file: PosixPath ('example.txt' )

Question

我正在使用 Python 3 的 pathlib模块，像这样:

from pathlib import Path

filename = Path(__file__).parent / "example.txt"
contents = open(filename, "r").read()

但我在某些机器上收到此错误:

TypeError: invalid file: PosixPath('example.txt')

但在我的机器上它可以工作。

pathlib仅在 Python 3.6 及更高版本中与 open 无缝集成。来自 Python 3.6's release notes :

The built-in open() function has been updated to accept os.PathLike objects, as have all relevant functions in the os and os.path modules, and most other functions and classes in the standard library.

要让它在 Python 3.5 和 Python 3.6 中工作，只需将对象转换为字符串:

contents = open(str(filename), "r").read()
