Getting Error: spawn ./node_modules/.bin/grunt ENOENT when running grunt

I have a project that is started in development by

yarn start

It runs a index.js that starts a grunt process and get this error: 

$ yarn start
yarn start v0.23.2
$ node ./development
grunt_arguments [ '--force', '--notify', '--verbose', '--debug', '--stack' ]
=======================================
Open http://localhost:8000 to start developing

events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: spawn ./node_modules/.bin/grunt ENOENT

I usually monkey patch child_process to help me debug that kind of issues. Add something like this in the beginning of your index.js file:

const util = require('util')
const childProcess = require("child_process");

const originalSpawn = childProcess.spawn;

childProcess.spawn = function() {
    console.trace('SPAWN');
    console.log('ARGS');
    console.log(util.inspect(arguments, false, null)); // showHidden = false, depth = null

    return originalSpawn.apply(this, arguments);
};

If your run, childProcess.spawn('ls', ['-lh', '/usr']) you will see something like:

Trace: SPAWN
    at Object.childProcess.spawn (repl:2:9)
    at myFunction (repl:2:14)
    at repl:1:1
    at REPLServer.defaultEval (repl.js:164:27)
    at bound (domain.js:250:14)
    at REPLServer.runBound [as eval] (domain.js:263:12)
    at REPLServer.<anonymous> (repl.js:392:12)
    at emitOne (events.js:82:20)
    at REPLServer.emit (events.js:169:7)
    at REPLServer.Interface._onLine (readline.js:210:10)
ARGS
{ '0': 'ls', '1': [ '-lh', '/usr' ] }

Maybe after running it you can update your question with the new information.
