TS2307: Cannot find module 'ionic/ionic'

Ionic Framework ionic-v3
2

Have you tried to update the webpack.config.js?

resolve: {
alias: {
  'ionic': 'ionic-framework',
  'web-animations.min': 'ionic-framework/js/web-animations.min',
},
extensions: ["", ".js", ".ts"]
}

I had the same issue too. Either you add the ionic alias like the above or you do import {Page} from "ionic-framework/ionic"
