WebpackJsonp missing after Ionic 3 update

Question

I recently bumped up to ionic 3 from 2. I can build my app for iOS, but ionic serve fails now with the error below.

Before I could build for iOS, I had to manually replace main.prod.ts and main.dev.ts with main.ts

Would you need any more info to be able to help?

Answer 1

I did this :

rm -rf node_modules
added <script src="build/vendor.js"></script> in index.html
npm install -g ionic@latest
npm install @ionic/app-scripts@latest --save-dev
npm install ionic-angular@latest --save
npm upgrade for upgrade all modules.
This worked and now everything runs well
