Trying to install Ionic 2 (npm ERR!)

I created a project folder with ionic 2, but when I launch the “ionic serve” command i get this error:

I’ve installed:

  • Ionic 2.2.1
  • Node.js 6.9.4
  • npm 3.10.10
  • Cordova 6.5.0
    on a Win10 pc.

I also read other similar problems: I tried other versions of the listed softwares but no combination has solved the problem.

Does anyone know how to fix?

luca94, try this package.json …

  "name": "ionic-hello-world",
  "author": "Ionic Framework",
  "homepage": "",
  "private": true,
  "scripts": {
    "ionic:build": "ionic-app-scripts build",

    "typescript": "2.0.9"
  "cordovaPlugins": [
  "cordovaPlatforms": [],
  "description": "myApp_2016_11_22: An Ionic project"

Ok, with that package.json and launching:

> npm install @ionic/app-scripts@latest --save-dev
> npm rebuild node-sass

I get dev server running: http://localhost:8100/

…But… Now I have this error…

Runtime Error
Module build failed: Error: ENOENT: no such file or directory, open ‘C:\Users\admin\Desktop\myapp\src\app\main.js’ at Error (native)

Not sure, but think I fixed mine when updating my app-scripts by just deleting node_modules and run
npm install

done, but didn’t solve :disappointed:
