Angular2 Rxjs 404错误

尝试启动Angular2应用程序时出现以下错误：

Failed to load resource: the server responded with a status of 404 (Not Found)
angular2-polyfills.js:332 Error: Error: XHR error (404 Not Found) loading http://localhost:55707/rxjs(…)

这是我的index.html：

      System.config({

          app: {
            format: 'register',defaultExtension: 'js'
          },},});
      System.import('app/boot')
            .then(null,console.error.bind(console));
    </script>
</head>
<body>
    <app>Loading...</app>
</body>
</html>

boot.ts：

///<reference path="../node_modules/angular2/typings/browser.d.ts"/> 

import {App} from './app.component';
import {bootstrap}  from 'angular2/platform/browser';
import {ROUTER_PROVIDERS} from 'angular2/router';
import {HTTP_PROVIDERS} from 'angular2/http';
import {APP_PROVIDERS} from './app.module';

bootstrap(App,[
    //ROUTER_PROVIDERS,//HTTP_PROVIDERS,APP_PROVIDERS]);

我已经尝试在system.config中放置rxjs的路径(它不起作用)但是因为我使用的是rxjs包,所以我不应该这样做.

解决方法

问题出在你的streak-maker / src / StreakMaker.Web / App / message-board / message-board.service.ts文件中

您应该导入rxjs模块,因为它在Rxjs库中不存在：

import {Http} from 'angular2/http';
import {Injectable} from 'angular2/core';
import "rxjs"; // <-----

@Injectable()
export class MessageBoardService {
  constructor(private _http: Http) { }

  get() {
    return this._http.get('/api/messageboard').map(res => {
        return res.json();
    });
  }
}

您应该使用以下一个(rxjs / Rx)：

import {Http} from 'angular2/http';
import {Injectable} from 'angular2/core';
import "rxjs/Rx"; // <-----

@Injectable()
export class MessageBoardService {
  (...)
}

你是对的：包含Rx.js文件足以提供Rxjs模块. SystemJS.config中不需要其他(显式)配置.
