我正在尝试将基于旧 angular2 快速入门的应用迁移到新应用(具有新的文件夹层次结构(。
点击npm start时404 GET /app我收到错误。值得一提的是，我的app.module.ts文件被放置在/app/modules/app/app.module.ts
我试图改变路径，但没有运气，但我仍然怀疑这与我的配置有关。
主要.ts：
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/modules/app/app.module';
platformBrowserDynamic().bootstrapModule(AppModule);
systemjs.config.js：
/**
* System configuration for Angular samples
* Adjust as necessary for your application needs.
*/
(function (global) {
System.config({
paths: {
// paths serve as alias
'npm:': 'node_modules/'
},
// map tells the System loader where to look for things
map: {
// our app is within the app folder
app: 'app',
// angular bundles

},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
}
}
});

更改systemjs.config.js
在package条目中，将app更改为app: {main: 'app/modules/app/app.module', defaultExtension: 'js'}
如果您在某处创建了应用程序的捆绑包，则应将app键指向该捆绑包，而不是app.module 。
