node.js - Angular2 QuickStart NPM启动无法正常工作-LMLPHP

我知道Angular2 Beta刚刚发布,但是我无法从其官方网站教程(https://angular.io/guide/quickstart)中复制步骤。也许有人遇到过类似的问题,并且知道该怎么做才能解决此问题?当我尝试使用npm start命令启动应用程序时,我得到如下输出:

18 error This is most likely a problem with the angular2-quickstart package,

18 error Tell the author that this fails on your system:

18 error You can get their info via:
18 error     npm owner ls angular2-quickstart
18 error There is likely additional logging output above.
19 verbose exit [ 1, true ]

我有:
typescript 1.7.5版本
节点0.12.2版本

也许有人可以帮助解决问题:)?

app.components.ts:
import {Component} from 'angular2/core';

@Component({
    selector: 'my-app',
    template: '<h1>My First Angular 2 App</h1>',
})

export class AppComponent {}

boot.js:
import {bootstrap} from 'angular2/platform/browser'
import  {AppComponent} from './app.component'

bootstrap(AppComponent);

最佳答案

将package.json中的start字段更改为

"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" "


"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "
