Lösung:
Man muss das Angular Modul in der Angular
app.component.ts Datei eintragen an zwei Stellen
1: im Import oben im Header
import { AngularFireDatabaseModule } from '@angular/fire/database';
und
2: im @NgModule imports Bereich
imports: [
BrowserModule,
AngularFireModule.initializeApp(firebaseConfig),
AngularFireDatabaseModule
],
