Angular最新beta.0错误：错误：（15,25）TS2304：找不到姓名＆＃39; Http＆＃39;。试过像

这样的差异

import {Http} from 'angular2/core';
import {Http} from 'angular2/core';
import {Http} from 'angular2/http.dev';
import {Http} from 'angular2/bundles/http';

一切都没有运气:(

这是我的组件：

  ///<reference path="../../typings/es6-promise/es6-promise.d.ts"/>
///<reference path="../../typings/zone.js/zone.js.d.ts"/>

import {Component} from 'angular2/core';
import {Injectable} from 'angular2/core';
import {Inject} from 'angular2/core';
import {HTTP_PROVIDERS, Http} from 'angular2/http';

@Component({
    providers: [HTTP_PROVIDERS]
})

@Injectable()
export class MyService {
    private _val:number;

    constructor(@Inject(Http) http:Http) {
        this._val = Math.random();
    }

    public showAlert() {
        alert(`here is an alert ${this._val}`);
    }
}

从ng2 beta开始需要将我的system.js更改为

 <script>
System.config({
  defaultJSExtensions: true,
  transpiler: 'typescript',
  packages: {
    'component': {defaultExtension: 'ts'}
  },
  typescriptOptions: {emitDecoratorMetadata: true}
});
System.import('./component/App.ts')

希望它可以帮助某人...
