Question

我根据this tutorial修改了app / main.ts，当我＆＃34; npm开始＆＃34;我收到以下错误：

这是包含提交消息error的项目文件：https://github.com/monajalal/angular2_projects

import {bootstrap}    from '@angular/platform-browser-dynamic';
import {AppComponent} from '@angular/core'

@Component({
    selector: 'my-app',
    template: '<h1>Ultra Racing</h1>'

})
class AppComponent{}
bootstrap(AppComponent);

错误：

Monas-MacBook-Pro:my-proj mona$ npm start

> angular2-quickstart@1.0.0 start /Users/mona/angular/my-proj
> tsc && concurrently "tsc -w" "lite-server"

在你的主页中，你应该：

import { bootstrap }    from '@angular/platform-browser-dynamic';
import { AppComponent } from './app.component';

bootstrap(AppComponent);

参考：https://angular.io/guide/quickstart

我修改了app/app.component.ts：从'@ angular / core'导入{Component};

@Component({
    selector: 'my-app',
    template: "<h1>Mona's first Angular 2 App</h1>"
})
export class AppComponent { }

这是因为'在Mona之后我不得不使用'来修复它。它是由Angular Gitter频道的Google的“Rob Wormald”告诉我的。

错误的ERR！在angular2-quickstart@1.0.0启动脚本＆＃39; tsc＆amp;＆amp;同时＆＃34; tsc -w＆＃34; ＆＃34; LITE-服务器＆＃34;
