加载资源 angular2-cookie 失败答案

【问题标题】：Failed to load resource angular2-cookie加载资源 angular2-cookie 失败

【问题描述】：

我正在尝试使用 Visual Studio 在 angular-2 的快速启动中添加“angular2-cookie”。

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'));

应用程序构建良好，但最终出现加载资源失败：服务器响应状态为 404（未找到）

错误：(SystemJS) XHR 错误 (404 Not Found) loading http://localhost:56249/angular2-cookie/services/cookies.service(...)

我错过了什么？

系统配置：

 System.config({
paths: {
  // paths serve as alias
  'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
  // our app is within the app folder
  app: 'app',

  // angular bundles
  '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
  '@angular/common': 'npm:@angular/common/bundles/common.umd.js',

  'angular-in-memory-web-api': 'npm:angular-in-memory-web-api',
  'angular2-cookie': 'npm:angular2-cookie'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
  app: {
    main: './main.js',
    defaultExtension: 'js'
  },
  rxjs: {
    defaultExtension: 'js'
  },
  'angular-in-memory-web-api': {
    main: './index.js',
    defaultExtension: 'js'
  },
  'angular2-cookie': {
  main: './core.js',
  defaultExtension: 'js'
  }
}  });

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'));

}

}

同样的代码今天也可以使用。似乎重建，删除浏览器缓存有帮助。
