¥The fs.watch API is not 100% consistent across platforms, and is unavailable in some situations.

在 Windows 上，如果监视目录被移动或重命名，则不会触发任何事件。删除监视目录时报 EPERM 错误。

¥On Windows, no events will be emitted if the watched directory is moved or renamed. An EPERM error is reported when the watched directory is deleted.
