Ionic Angular 中没有 Camera-Injection-Error 的提供者（在 Module.ts 中有提供者）

Question

im trying to make an app with ionic-angular using ionic/ngx camera, but I keep getting this error in spite of adding the camera provider in the module.ts section.

This is the error

And this is my module.ts

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { RouteReuseStrategy } from '@angular/router';


    import { IonicModule, IonicRouteStrategy } from '@ionic/angular';

    import { AppComponent } from './app.component';
    import { AppRoutingModule } from './app-routing.module';

    import { IonicStorageModule } from '@ionic/storage-angular';
    import {AuthGuardService} from './services/auth-guard.service';
    import {AuthenticationService} from './services/authentication.service';
    import {Storage} from '@ionic/Storage';
    import { HttpClientModule } from '@angular/common/http';
    import { QRCodeModule } from 'angularx-qrcode';
    **import { Camera } from '@ionic-native/camera/ngx';**


    @NgModule({
    declarations: [AppComponent],
    imports: [ BrowserModule, IonicModule.forRoot(), AppRoutingModule,IonicStorageModule.forRoot(),                         QRCodeModule],
    providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }, **Camera**],
    bootstrap: [AppComponent],
    })
    export class AppModule {}

The method im trying to pull of is this one

 export class PhotoService{
  constructor(private camera: Camera){}




    takePicture(){
      const fotito = Image;
      const options: CameraOptions ={
        quality: 100,
        destinationType: this.camera.DestinationType.DATA_URL,
        encodingType: this.camera.EncodingType.JPEG,
        mediaType: this.camera.MediaType.PICTURE,
      }


    this.camera.getPicture(options).then((imageData) => {imageData= fotito

    },(err) =>{console.log('Problemas de camara' + err);

  })
  return(fotito);
 }
}

You need to provide the Camera in the module that uses the camera plugin, You have it place incorrectly in the app.component, move it to the component that uses the camera.
