Cannot resolve module 'es6-shim/es6-shim.min'


I just got latest on the ionic-conference-app and when I run ionic serve I get following error:


I noticed the webpack.config.js makes reference to ‘es6-shim/es6-shim.min’ in module.exports.

Your system information:

Cordova CLI: 5.3.3
Gulp Version: CLI version 3.8.11
Gulp local:
Ionic Version: 2.0.0-alpha.42
Ionic CLI Version: 2.0.0-beta.12
Ionic App Liv Version: 2.0.0-beta.6
OS: Windows 10
Node Version: v5.1.1

Anybody else having a similar issue?

I ran npm install from the project root again and it fixed my problem by updating all the missing node-modules
