Error while grunt serve command - angularjs

Question

I have created my application in angularJS. After npm install and bower install I am getting this error on grunt serve
I am using npm 2.7.4, bower 1.6.5, grunt-cli v0.1.13 and grunt v0.4.5.
My grunt file is:
// Generated on 2013-10-20 using generator-angular 0.4.0
'use strict';
var LIVERELOAD_PORT = 35729;
var lrSnippet = require('connect-livereload')({ port: LIVERELOAD_PORT });
var mountFolder = function (connect, dir) {
return connect.static(require('path').resolve(dir));
};
var proxySnippet = require('grunt-connect-proxy/lib/utils').proxyRequest;
// # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to recursively match all subfolders:
// 'test/spec/**/*.js'
module.exports = function (grunt) {
require('load-grunt-tasks')(grunt);
require('time-grunt')(grunt);
// configurable paths
var yeomanConfig = {
app: 'app',

I updated my package.json
added "eventemitter3": "^0.1.6"
and updated the version of grunt-connect-proxy from 0.1.6 to 0.2.0.
It worked for me
