再利用可能なコンポーネントを作成して、単一のjsファイルにバンドルし、異なる角度2のアプリケーションと共有することができます。しかし、私は得続けるError: (SystemJS) Unexpected value 'undefined' declared by the module 'AppModule'再利用可能な角度2のコンポーネントを複数のアプリケーションにバンドルするにはどうすればよいですか？
私はgulpを使って私のパッケージを作る。
build/pkg/basic.js (this is my reusable package)
build/app/main.js (this is one test app trying to use the package)
build/app/app.module.js
build/app/app.component.js
build/systemjs.config.js
build.index.html
私は（私はdevのツールでファイルを見ることができます）PKG/basic.jsは、ウェブページを経由してダウンロードさないことを知っている：出力は次のようになります。
main.ts
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
const platform = platformBrowserDynamic();
platform.bootstrapModule(AppModule);
app.module.ts
import { BasicComponent } from 'basic/basic.component';
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
@NgModule({
imports: [ BrowserModule ],
declarations: [ AppComponent, BasicComponent],
bootstrap: [ AppComponent, BasicComponent]
})
export class AppModule { }
app.component.ts
import { BasicComponent } from 'basic/basic.component';
import { Component } from '@angular/core';
@Component({
selector: 'my-app',
template: '<h1>My First Angular App</h1><basic></basic>'
})
export class AppComponent { }
basic.component.ts（私の再利用可能なコンポーネントパッケージ）
import { Component } from '@angular/core';
@Component({
selector: 'basic',
template: 'HI BASIC'
})
export class BasicComponent { }
