Trying to build a simple Angular 2 app with modal dialogs using 'ng2-bs3-modal'

app/main.ts
import {bootstrap} from 'angular2/platform/browser' // 导入引导 import {AppComponent} from './app.component' // 导入我们刚刚创建的组件 从'./a.component'导入{AComponent} // //从'./user-login.component'导入{UserLoginModalComponent} //
引导程序（应用程序组件）； // 最后引导它。 引导程序（AComponent）； //bootstrap(UserLoginModalComponent);
-
app/app.component.ts
import {Component} from 'angular2/core'; // <-- importing Component from core //import {AComponent} from './a.component'; @Component({ selector: 'my-app', //<----the element defined in the index.html template: '<h1>Angular2, Hello {{name}}</h1><br>' // <---this is the template to put in the component. // directives: [AComponent], }) export class AppComponent { name: string; constructor(){ this.name = "ANIL"; } } // <--- we need to export the class AppComponent. -
app/a.component.ts
import {Component} from 'angular2/core'; // <-- importing Component from core //import {AComponent} from './a.component'; @Component({ selector: 'my-app', //<----the element defined in the index.html template: '<h1>Angular2, Hello {{name}}</h1><br>' // <---this is the template to put in the component. // directives: [AComponent], }) export class AppComponent { name: string; constructor(){ this.name = "ANIL"; } } // <--- we need to export the class AppComponent. -
app/user-login.component.ts
import {Component} from 'angular2/core'; import {MODAL_DIRECTIVES, ModalComponent} from 'ng2-bs3-modal/ng2-bs3-modal'; @Component({ selector: 'user-login-modal', directives: [MODAL_DIRECTIVES], template: ` <modal #modal [keyboard]="false" [backdrop]="'static'"> <modal-header [show-close]="false"> <h4 class="modal-title">I am a modal!</h4> </modal-header> <modal-body> Hello World! </modal-body> <modal-footer [show-default-buttons]="true"></modal-footer> </modal> ` }) export class UserLoginModalComponent { @ViewChild(ModalComponent) modal: ModalComponent; open(){ this.modal.open(); } close(){ this.modal.close(); } }
我看到 ng2-bs3-modal 模块仍在尝试访问 @angular/core，我认为它应该指向 angular2/core？ 我还尝试在系统配置 js 中添加“地图”，但在访问 @angular/core 时它没有采用“.js”扩展名（即使系统配置 js 中存在 defaultExtension：“js”）。
请帮忙！！！
