Hi everybody,
I have the same problem as described in Ionic 3 Error.
I’ve already tried to remove npm, ionic and cordova completely with a fresh install.
ionic info
Cordova CLI: 6.5.0
Ionic Framework Version: 3.0.1
Ionic CLI Version: 2.2.2
Ionic App Lib Version: 2.2.1
Ionic App Scripts Version: 1.3.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Linux 4.4
Node Version: v6.10.2
Xcode version: Not installed
How I upgraded from ionic 2 to ionic 3: https://www.youtube.com/watch?v=oQJMUOznMrA
I’ve included the BrowserModule and ErrorHandler in my app.module.ts like this
import { ErrorHandler, NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
…
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
…
providers: [
{ provide: ErrorHandler, useClass: IonicErrorHandler }
]
But it won’t work.
Even in a blank starter template (-v3) it won’t work).
The error is allways the same:
Need some help
