修正方法は？
コア ライブラリ:
- 角度 2
- Angular 2 ブートストラップ
ビルドシステム:
ここに私のソースコードがあります:
Angular 2 ブートストラップ'alert.component.ts'
コードのこの部分はng2-bootstrapフレームワークに属します。
@Component({
selector: 'alert',
directives: [NgIf, NgClass],
template: ALERT_TEMPLATE
})
export class Alert {
......
}
私のプロジェクト アプリ コンポーネント
.... Other imports ....
import {Alert} from 'ng2-bootstrap/ng2-bootstrap';
@Component({
selector: 'app',
providers: [],
directives: [Alert], // <----- THE PROBLEM IS HERE
pipes: [],
styles: [require('./app.component.scss')],
template: require('./app.component.html')
})
@RouteConfig([
{path: '/', name: 'Index'}
])
export class App extends Type {
title: string = 'Hello';
constructor() {
super();
}
}
ブートストラップ スクリプト
ブートストラップ スクリプトの完全なソース コードはこちら
export function main() {
return browser.bootstrap(App)
.catch(err => console.error(err));
}
