fs.existsSync(path)


    如果路径存在则返回 true,否则返回 false

    Returns true if the path exists, false otherwise.

    For detailed information, see the documentation of the asynchronous version of this API: fs.exists().

    fs.exists() is deprecated, but fs.existsSync() is not. The callback parameter to fs.exists() accepts parameters that are inconsistent with other Node.js callbacks. fs.existsSync() does not use a callback.

    import { existsSync } from 'node:fs';
    
    if (existsSync('/etc/passwd'))
      console.log('The path exists.');
