Angular 4 - Please include either "BrowserAnimationsModule" or "NoopAnimationsModule" in your application

Question

I'm having a problem when I launch my Angular app on my browser. Everything works code speaking but I'm still getting this error:

Found the synthetic property @routerAnimations. Please include either BrowserAnimationsModule or NoopAnimationsModule in your application.

I already checked the posts on this subject and there's quite a lot but all of them answered the same:

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

and include it in the app module's imports.

imports: [
    BrowserAnimationsModule,
    ... 
]

That's what I did but still got the same error. I've been looking for hours for this solution. Anyone knows what could fix it ? Thanks

Here's my package.json:

Yes I did, it's already there when you generate the project with angular-cli — Messerschmitt, Oct 11 '17 at 08:12
Yes sir it's there, to be sure i even deleted the node_modules folder and ran "npm install" — Messerschmitt, Oct 11 '17 at 08:15
Do you use Angular CLI? You should clean the cache and re-install Angular CLI. — Ha Hoang, Oct 11 '17 at 08:37
I'm not sure but you still get the error when you create new project using angular-cli? — Ha Hoang, Oct 11 '17 at 09:37
@Messerschmitt could you show your code for using @routerAnimations? — Ha Hoang, Oct 11 '17 at 10:09
@HaHoang I just posted the solution to the mistake I made. Thanks man anyway I appreciate it — Messerschmitt, Oct 11 '17 at 12:39

Adding the lines

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

and

imports: [
    BrowserAnimationsModule,
    ... 
]

to app.module.ts actually solves it

One point is definitely you need to add BrowsersAnimationModule in your active Module. But apart from that you need to mention animations for that Synthetic selector (here @routerAnimations) which is Angular Component Meta

@Component({
  selector: 'app-card-grid',
  templateUrl: './card-grid.component.html',
  styleUrls: ['./card-grid.component.scss'],
  animations: [
    trigger('routerAnimations', [
      state('collapsed', style({ height: '0px', minHeight: '0' })),
      state('expanded', style({ height: '*' })),
      transition('expanded <=> collapsed', animate('225ms cubic-bezier(0.4, 0.0, 0.2, 1)')),
    ]),
  ],

Sidenav won't work unless you import BrowserAnimationsModule. So import it from '@angular/platform-browser/animations'.

I solved the issue, the problem was the "@routerAnimations" in my app.component.html:

<div [@routerAnimations]="myOutlet.state">
    <router-outlet #myOutlet></router-outlet>
</div>

When I removed it, everything worked just fine

removing synthetic property do not solve your actual issue. since, you need that, hence, you added `BrowserAnimationsModule` at first place. – Sumit Ramteke Aug 15 '20 at 10:17
