无法加载资源 angular2-cookie

Question

我正在尝试使用 visual studio 在 angular-2 的快速启动中添加 'angular2-cookie'。

正在关注 https://www.npmjs.com/package/angular2-cookie

到目前为止，我已经进行了以下更改。

npm install angular2-cookie --save

System.config
  map: 
   // other libraries
    'angular2-cookie': 'npm:angular2-cookie'

  packages:'angular2-cookie': {
  main: './core.js',
  defaultExtension: 'js'
  }

  app.component.ts

    import { CookieService } from 'angular2-cookie/services/cookies.service';

    providers: [CookieService]

   constructor(private _cookieService: CookieService) {
    _cookieService.put("test.com", "testCookie");
    console.log(_cookieService.get('test.com'));

应用程序构建正常，但最终加载资源失败：服务器响应状态为 404（未找到）

错误：(SystemJS) XHR 错误（404 未找到）加载 http://localhost:56249/angular2-cookie/services/cookies.service(…)

我错过了什么？

app.component.ts

import { Component } from '@angular/core';
import { CookieService } from 'angular2-cookie/services/cookies.service';


@Component({
selector: 'my-app',
template: '<h1>Quickstart for angular</h1><div> Hello there!</div>',
providers: [CookieService]

})
export class AppComponent {

constructor(private _cookieService: CookieService) {
    _cookieService.put("test.com", "testCookie");
    console.log(_cookieService.get('test.com'));

}

}

相同的代码今天可以使用。似乎重建、删除浏览器缓存有帮助。
