import {Component} from 'angular2/core';
@Component({

template: `<h1>My First Angular 2 App</h1>`
})
export class AppComponent {
}
我的 boot.ts ：
import {bootstrap} from 'angular2/platform/browser';
import {AppComponent} from './app.component';
bootstrap(AppComponent);
我的 index.html的：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Angular 2 Quick Start</title>
<script src="node_modules/es6-shim/es6-shim.js"></script>
<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<script src="node_modules/rxjs/bundles/Rx.js"></script>
<script src="node_modules/angular2/bundles/angular2.dev.js"></script>
<script>
System.config({
packages: {
format: 'register',
defaultExtension: 'js'
}
});
System.import('app/boot')
.then(null, console.error.bind(console));
</script>
</head>
<body>

},
"exclude": [
"node_modules"

推荐答案
尝试更换此
System.config({
packages: {
format: 'register',
defaultExtension: 'js'
}
});
本
System.config({
packages: {
app: { // must match your folder name
format: 'register',
defaultExtension: 'js'
}
}
});
我是想稍微不同的文件夹结构适用于他们的快速启动，并跑进了同样的问题。我发现，包对象的属性名称必须匹配父文件夹。
I was trying to apply a slightly different folder structure to their quickstart and ran into the same issue. I found that the name of the property on the "packages" object had to match the parent folder.
