Babel and Deploy Nodejs to Google App Engine - node.js

Question

I'm a newbie nodejs. I have a trouble about deploying nodejs app to google app engine. This is my error, I have been trying to fix it but it's not work. I've installed babel.
Bug
Updating service [default]...failed.
ERROR: (gcloud.app.deploy) Error Response: [9]
Application startup error:
restaurant_api#1.0.0 prestart /app
npm run -s build
You have mistakenly installed the babel package, which is a no-op in Babel 6.
Babel's CLI commands have been moved from the babel package to the babel-cli package.
npm uninstall babel
npm install --save-dev babel-cli
This is my package.json

Problem is quite simple, if you notice clearly GAE, does not install dev-dependencies. So move your dev-deps above inside deps , like I did and babel no found error is gone.

Answer 2

The clue is in the error message.
In your devDependencies section, you already have babel-cli included.
However, your dependencies section still has a reference to "babel": "^6.23.0".
Either remove this line, or replace it with babel-cli, leaving you with:
"dependencies": {
"babel-cli": "^6.23.0",
"body-parser": "^1.17.0",
"express": "^4.15.0",
"express-jwt": "^5.1.0",
"jsonwebtoken": "^7.3.0",
"mongoose": "^4.8.5",
"passport": "^0.3.2",
"passport-local": "^1.0.0",
"passport-local-mongoose": "^4.0.0",
"pm2": "^2.4.2"
},

Answer 3

You need to install babel-cli globally, i.e. run the command "npm install babel-cli -g" as part of your build npm script, or create a pre-install script that install it if you want to keep it more organized in case you need to add more things later on.
"scripts": {
"dev": "NODE_ENV=development nodemon -w src --exec \"babel-node src --presets es2015,stage-0\"",
"build": "npm install bable-cli -g && babel src -s -D -d dist --presets es2015,stage-0",
