TS2339: Property 'debounceTime' does not exist on type 'Observable<any>'. - Angular 6

 【出现的问题】TS2339: Property 'debounceTime' does not exist on type 'Observable<any>'.


【解决方法】

第一步,在 Terminal 更新 Angular

ng update

第二步,fix the rxjs

npm i -g rxjs-tslint

第三步,修改代码,不再使用debounceTime(500),而是在外边添加 .pipe(),即变成.pipe(debounceTime(500))

this.titleFilter.valueChanges
      .pipe(debounceTime(500))
      .subscribe( 
        value => this.keyword
      );
