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

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
