【问题描述】：
我正在尝试学习 angular2，但是我坚持使用 SystemJS 配置。

System.config({
packages: {
app: {

defaultExtension: 'js',
main: 'main.js'
},
'@angular/core': {
main: 'bundles/core.umd.js',
defaultExtension: 'js'
},

main: 'bundles/compiler.umd.js',
defaultExtension: 'js'

'@angular/common': {
main: 'bundles/common.umd.js',
defaultExtension: 'js'

'@angular/platform-browser-dynamic': {
main: 'bundles/platform-browser-dynamic.umd.js',
defaultExtension: 'js'
},
'@angular/platform-browser': {
main: 'bundles/platform-browser.umd.js',
defaultExtension: 'js'
},
rxjs: {
main: 'bundles/Rx.umd.min.js',
defaultExtension: 'js'

},
map: {
'app': '.', // where my app is. '.' means relative
'@angular': '/js/node_modules/@angular',
'rxjs': '/js/node_modules/rxjs'

System.import('management/main')
.then(null, console.error.bind(console));
</script>
<!-- end AngularJS 2-->
</head>
<body>
<my-app>Loading...</my-app>
</body>
</html>
我的文件结构是：
management/
├── app/
│ ├── app.component.ts
| ├── root.module.ts
├──main.ts
main.ts：
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import {RootModule} from "./app/root.module";
platformBrowserDynamic().bootstrapModule(RootModule);
root.module.ts：
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
@NgModule({
imports: [BrowserModule], // what my Angular Application needs
declarations: [AppComponent], // the view classes that belong to this module.
bootstrap: [AppComponent], // which class to boostrap
})
export class RootModule {}
app.component.ts：
import {Component} from '@angular/core';
@Component({
selector: 'my-app',
template: '<h1>BLAAH is best !!! OMGOMGOMG blagh assdsdasd</h1>'
})
export class AppComponent { }
我已阅读 systemjs 提供的所有文档，但似乎无法理解配置中发生了什么。
例如，如果我写：
System.import('main')
.then(null, console.error.bind(console));
我在控制台中收到这些错误？
GET http://merchant.localhost:1337/main.js 404 (Not Found)
Error: (SystemJS) XHR error (404 Not Found) loading http://merchant.localhost:1337/main.js(…)

我变了：
System.config({
packages: {
app: {
format: 'register',
defaultExtension: 'js',
main: 'main.js'
},
'@angular/core': {
main: 'bundles/core.umd.js',
defaultExtension: 'js'
},
'@angular/compiler': {
main: 'bundles/compiler.umd.js',
defaultExtension: 'js'
},
'@angular/common': {
main: 'bundles/common.umd.js',
defaultExtension: 'js'
},
'@angular/platform-browser-dynamic': {
main: 'bundles/platform-browser-dynamic.umd.js',
defaultExtension: 'js'
},
'@angular/platform-browser': {
main: 'bundles/platform-browser.umd.js',
defaultExtension: 'js'
},
rxjs: {
main: 'bundles/Rx.umd.min.js',
defaultExtension: 'js'
}
},
map: {
'app': 'management', // where my app is. '.' means relative
'@angular': '/js/node_modules/@angular',
'rxjs': '/js/node_modules/rxjs'
}
});
System.import('app')
.then(null, console.error.bind(console));
所以现在我的应用程序位于管理文件夹中，我用“app”启动它，它知道它必须运行 main.js 等等。这行得通。伟大的。所以我继续创建了一个 root.component.html 现在没有加载。 这是代码：
root.component.ts：
import {Component} from '@angular/core';
@Component({
selector: 'root-component',
templateUrl: 'root.component.html'
})
export class RootComponent { }
还有错误：
GET http://merchant.localhost:1337/root.component.html 404 (Not Found)
