当我在目录上使用 fs.watch 时： https ://nodejs.org/docs/latest/api/fs.html#fs_fs_watch_filename_options_listener
在调用 fs.watch 后，它不会注意到添加到目录中的新文件。我在 Linux 上 - 我需要进行一些调用以通知新添加/删除的文件吗？
返回对象 FSWatcher 上的唯一事件是“更改”、“错误”和“关闭”——文件有“添加”或“删除”。
interface FSWatcher extends events.EventEmitter {
close(): void;
/**
* events.EventEmitter
* 1. change
* 2. error
*/
addListener(event: string, listener: (...args: any[]) => void): this;
addListener(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
addListener(event: "error", listener: (error: Error) => void): this;
addListener(event: "close", listener: () => void): this;
on(event: string, listener: (...args: any[]) => void): this;
on(event: "change", listener: (eventType: string, filename: string | Buffer) => void): this;
