Errors trying to deploy to phone

Ionic Framework ionic-v3

Does anyone know why it would be throwing this exception ? I can’t even tell where to begin looking

core.js:1350 ERROR Error: Uncaught (in promise): Error: StaticInjectorError[Router]:

“No provider for Router!”:

3

This error is thrown as you can see in the stack trace before the app bootstraps…

I have the following following import:

import { RouterModule, Router } from “@angular/router”;

I’m not even using Router in any of my code so I don’t know where this is coming from…

Are you using Ionic 3 or 4?

If you are not using @angular/router then comment out this line:

// import { RouterModule, Router } from “@angular/router”;

Delete your /node_modules directory and then:

npm install
ionic serve

Then try:

npm run build --prod
npm install http-server -g
http-server ./www
