找不到模块：错误：无法解析Angular 6中的“./package”

在我的组件文件中,使用了示例中给出的代码

import { Component,OnInit } from '@angular/core';

import scraperjs from 'scraperjs';

@Component({
  selector: 'app-express',templateUrl: './express.component.html',styleUrls: ['./express.component.css']
})
export class ExpressComponent implements OnInit {

  constructor() { }

  ngOnInit() {
    this.aliExpress();
  }

  aliExpress() {
    console.log('loaded ali express');

    scrapperjs.StaticScraper.create('https://news.ycombinator.com')
      .scrape(function ($) {
        return $('.title a').map(function () {
          return $(this).text();
        }).get();
      }).then(function (news) {
      console.log(news);
    });
  }

}

但它给出了错误

Failed to compile.
