我已将其精简为最基本的数据，但我对发生的事情感到困惑。我在 Angular 2 中收到选择器未找到错误。试图找出问题所在，它在一小时前工作，现在我添加了逗号或空格或做了一些事情来打破它，但我无法弄清楚我改变了什么!安排
感谢任何帮助!谢谢!
boot.ts
import {bootstrap} from 'angular2/platform/browser';
import {AppComponent} from './app.component';
bootstrap(AppComponent);
app.component.ts
import {Component} from 'angular2/core';
@Component({
selector: 'app',
template: `
<h1>component works!</h1>
`
})
export class AppComponent {
}

System.config({

});
System.import('app/boot')
.then(null, console.error.bind(console));

最佳答案
在您的 html 文件中，您需要更改 <my-app>至<app>
....
</head>
<body>
<app>Loading...</app> <!-- this should match your root component selector -->
<script>
....
