and my package.json file is-

{
  "name": "nodejs-web-app1",
  "version": "0.0.0",
  "description": "NodejsWebApp1",
  "main": "server.js",
  "scripts": {
    "start": "node server.js"
  },
  "author": {
    "name": "ddfps"
  },
  "dependencies": {
    "body-parser": "^1.17.1",
    "ejs": "^2.5.6",
    "express": "^4.15.2",

    "morgan": "^1.8.1",
    "node-gcm": "^0.14.6",
    "socket.io": "^1.7.4"
  }
}

what could cause the problem?

p.s I've got the exact same error when ran through cloud.9
