angular5 – ngx-webcam用于特定视图和分量角6

我在我的应用程序中使用ngx-webcam来使用网络摄像头捕获图像.我在app.module.ts中有导入库,也在我的视图中,但它给了我这个错误
‘webcam’不是一个已知的元素.如果在app.component html中使用网络摄像头标签,它工作正常,但我想在单独的视图中使用它.这是我的代码

import {WebcamImage} from 'ngx-webcam';

export class CreateMemberComponent implements OnInit {
 private trigger: Subject<void> = new Subject<void>();

 // latest snapshot
 public webcamImage: WebcamImage = null;
public triggerSnapshot(): void {
    this.seconds = 3;
    this.trigger.next();
    this.seconds = null;
  }

  public handleImage(webcamImage: WebcamImage): void {
    console.log('received webcam image',webcamImage);
    this.webcamImage = webcamImage;
  }

  public get triggerObservable(): Observable<void> {
    return this.trigger.asObservable();
  }

这是我的HTML代码

<div class="col-sm-4">
    <div style="text-align:center">
        <div>
          <p>{{seconds}}</p>
          <webcam [trigger]="triggerObservable" (imageCapture)="handleImage($event)"></webcam>
          <br/>
          <button id="snapshotBtn" (click)="triggerSnapshot();">Take A Snapshot</button>
        </div>
      </div>
      <div class="snapshot" *ngIf="webcamImage">
        <h2>Nice one!</h2>
        <img [src]="webcamImage.imageAsDataUrl"/>
      </div>
</div>

请参阅附图以供参考.

import {WebcamModule} from 'ngx-webcam';

@NgModule({
  imports: [
    WebcamModule
  ],declarations: [CreateMemberComponent,UpdateMemberComponent,MembersListComponent]
})
export class MembersProfileModule { }
