Angular6属性'debounceTime'在'Observable <any>'类型中不存在？

Question

在Angular更新指南之后我将Angular 5项目更新为Angular 6后 我得到了.

Property 'debounceTime' does not exist on type 'Observable<any>'

运行后ng update我的所有组件丢失了debounceTime import.但我手动把它放回去,但这并没有解决问题.

example.component.ts

import { debounceTime } from 'rxjs/operators';
 //Added after removed by ng update

 this.searchField.valueChanges
  .debounceTime(800)
  .distinctUntilChanged()
  .subscribe(term => {
    this.searchText = term;
    this.getAllDoctors();
  },

我真的想了解这里发生的事情.

您需要使用管道操作员.

this.searchField.valueChanges
  .pipe(debounceTime(800),
        distinctUntilChanged()
   )
  .subscribe(term => {
    this.searchText = term;
    this.getAllDoctors();
  }),
