问题 如何解决Nodejs：错误：ENOENT：没有这样的文件或目录

我有一个Nodejs Web应用程序当前正在服务器上成功运行。现在我正在尝试在我的开发服务器上设置本地副本。

我目前有Nodejs，NPM和Mongo安装就像我在生产服务器中安装的那样但是当我尝试启动节点服务器时出现以下错误

什么可能导致这个问题？

embah@devsertwo:~/node/nodeapp$ node app.js
fs.js:640
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^
