我的服务内部：
import { WebWorkerService } from 'angular2-web-worker';
constructor(localStorage: LocalStorageService, private _webWorkerService: WebWorkerService){
}
我收到错误：（SystemJS）XHR错误（404 Not Found）loading http://localhost:8000/node_modules/angular2-web-worker/dist 我也尝试过： 从'angular2-web-worker / web-worker.service'导入{WebWorkerService}; 但它没有奏效。问题是什么？ 提前谢谢。
