Ionic 3 Error

I just upgrade to latest ionic and fixed few errors. Now I got this error after ionic server. What does it mean and how can I troubleshoot?

found problem

import { BrowserModule } from ‘@angular/platform-browser’;

Was right in the error message:

:slight_smile:

Hi,

I also have the same problem.

I’ve included the BrowserModule in my app.module.ts like this

import { BrowserModule } from '@angular/platform-browser';

and

imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],

but it won’t work.

Even in a blank starter template (-v3) it won’t work). Also I tried to remove npm, cordova and ionic completely, no success.

Need some help :pensive:

You should post this in a new thread, including the error message and ionic info output, and not here in a “solved” thread.
