响应式编程时出现：error TS2339: Property 'debounceTime' does not exist on type 'Observableany'.

constructor() {this.searchInput.valueChanges//.debounceTime(500) 无法使用.pipe(debounceTime(1000)).subscribe( stockCode => this.getStockInfo(stockCode)) ;.....省略}

运行这段代码时提示：ERROR in src/app/bind/ponent.ts(25,8): error TS2339: Property ‘debounceTime’ does not exist on type ‘Observable’.

就是在Angular6中的rxjs 无法识别debounceTime（）方法，将debounceTime(1000)修改为pipe(debounceTIme(1000))即可，同时import {debounceTime} from ‘rxjs/operators’; 问题即可解决。
