angular - BrowserModule has already been loaded Error

Question

I've updated my application to RC6 and now i keep getting this error:

zone.js:484 Unhandled Promise rejection: BrowserModule has already been loaded. If you need access to common directives such as NgIf and NgFor from a lazy loaded module...

I'm using lazy loading and my application is broken up in to a lot of lazy loaded modules. However in RC5 everything worked fine.

The only change I've managed to find in the changelog for RC6 is this:

compiler: throw descriptive error meesage for invalid NgModule providers

But since i haven't seen any errors in RC5 this probably doesn't apply here.

I'm kind of out of ideas so any help is greatly appreciated.

I think you are using 'NoopAnimationsModule' or 'BrowserAnimationsModule', Which already contain 'BrowserModule' and loading your module lazily. SO the solution is Replace the BrowserModule with 'NoopAnimationsModule or 'BrowserAnimationsModule' in your 'app.module.ts'.

import { Router } from '@angular/router';
import { AdminsModule } from './admins/admins.module';
import { NoopAnimationsModule } from '@angular/platform-browser/animations';
//import { BrowserModule } from '@angular/platform-browser';
import { NgModule,OnInit } from '@angular/core';
import { AppComponent } from './app.component'; 
@NgModule({
    declarations: [
        AppComponent,
    ],
    imports: [
    //BrowserModule,
    NoopAnimationsModule,
    FormsModule
],
    providers: [],
    bootstrap: [AppComponent]
})
export class AppModule {}
