谷歌云平台：“找不到模块firebase-admin”

Question

I am trying to deploy my node.js server to google cloud platform. It works perfectly when I use it locally (run it with npm start of node app.js ).

But when I try to deploy it ( gcloud deploy ), it failed, and in the Log:

Error: Cannot find module 'firebase-admin' at Function.Module._resolveFilename (module.js:469:15) at Function.Module._load (module.js:417:25) at Module.require (module.js:497:17) at require (internal/module.js:20:19) at Object. (/app/app.js:28:16) at Module._compile (module.js:570:32) at Object.Module._extensions..js (module.js:579:10) at Module.load (module.js:487:32) at tryModuleLoad (module.js:446:12) at Function.Module._load (module.js:438:3)

in app.js i use simply:

var firebase = require("firebase-admin");

and this is my package.json file:

{
  "name": "Talk2Me-server",
  "version": "1.0.3",
  "main: "app.js",
  "description": "Talk2Me app server",
  "private": true,

Ok i managed to solve it,

first thing i reinstalled the packages using

npm install --save firebase-admin

and than i also did a little hack, i added to the package file:

  "scripts": {
    "start": "npm install firebase-admin; node app.js"
  },

which i guess isn't the best of practice, but it worked.
