Angular6 属性“debounceTime"在“Observable<any>"类型上不存在? [英] Angular6 Property 'debounceTime' does not exist on type 'Observable<any>'?

问题描述

按照Angular 更新指南将我的 Angular 5 项目更新为 Angular 6 后，我得到了.

After updating my Angular 5 project into Angular 6 following Angular update guide i'm getting.

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

运行 ng update 后，我的所有组件都丢失了 debounceTime 导入.但我手动放回了它，但这并没有解决问题.

after running ng update my all components lost the debounceTime import. But i put it back manually but that didn't fixed the issue.

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();
  },

我真的很想了解这里发生了什么.

I really want to understand whats going on here.

推荐答案

您需要使用管道运算符.

You need to use pipe operator.

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