Ionic3 staticInjectorError

Question

我需要一些关于ionic3和firebase中静态注入器错误的帮助。

我的问题是在页面构造函数中使用AngularFireAuth。像这样；

constructor(private windowSvc: WindowService,
public navCtrl: NavController,
public navParams: NavParams,
private autSvc: AuthenticationService,
private userSvc: UserService,
private angAuth: AngularFireAuth)

当我在构造函数中使用angularfireAuth时，我总是得到这样的错误信息：

ERROR Error: Uncaught (in promise): Error: StaticInjectorError(AppModule)[FirebaseApp -> InjectionToken FirebaseAppConfigToken]: 
  StaticInjectorError(Platform: core)[FirebaseApp -> InjectionToken FirebaseAppConfigToken]: 
    NullInjectorError: No provider for InjectionToken FirebaseAppConfigToken!

App.Module.ts：

@NgModule({
  imports: [
    BrMaskerModule,
    BrowserModule,
    IonicModule.forRoot(MyApp),
    AngularFireAuthModule, 
    AngularFireDatabaseModule
  ],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: ErrorHandler, useClass: IonicErrorHandler },
    AuthenticationService,
    UserService,
    WindowService,
    AngularFireAuth
  ]
})

我应该怎么做才能修复这个错误？

我解决了关于module.ts (而不是app.module.ts)的问题。当你创建一个页面时，让它不带模块。如果存在页面模块，则会给出该错误
