How to resolve Nodejs: Error: ENOENT: no such file or directory

I have a Nodejs web app currently running on a server successfully. Now I’m trying to setup a local copy on my Development server.

I currently have Nodejs, NPM and Mongo Installed just like what I have in production server however the error below occurs when I try to start node server

Whats could be causing this issue?

[email protected]:~/node/nodeapp$ node app.js
fs.js:640
  return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);
                 ^

Answer

Your app is expecting to find a file at /home/embah/node/nodeapp/config/config.json but that file does not exist (which is what ENOENT means). So you either need to create the expected directory structure or else configure your application such that it looks in the correct directory for config.json.
