我的Angular 2应用程序（TypeScript）有什么问题

Question

I have a component EventListComponent 我有一个组件EventListComponent

import { Component } from 'angular2/core';

@Component ({
    selector: 'el-events',
    templateUrl: 'app/events/event-list.component.html'
})

export class EventListComponent {
    pageTitle: string = 'Events List';
}

which should be rendered in AppComponent 应该在AppComponent中呈现

import { Component } from 'angular2/core';
import { EventListComponent } from './events/event-list.component';

@Component({
    selector: 'events-app',
    template: `
    <div>
        <h1>{{pageTitle}}</h1>
        <el-events></el-events>
    </div>`,
    directives: [ EventListComponent ]
})

export class AppComponent {
    pageTitle: string = 'Local Events App';
}

Directives, selectors, import/export and entire decorator is setuped correclty, IDE says. IDE说，正确设置了指令，选择器，导入/导出和整个装饰器。 Yes, I use old Angular 2 version with directives, that's a course requirements. 是的，我使用带有指令的旧Angular 2版本，这是课程的要求。

So, there's a problem - page doesn't show components. 因此，存在一个问题-页面未显示组件。 Here are errors: 错误如下：

And project tree is this: 项目树是这样的：

I discovered that error happens when I add directives , so maybe problem is here. 我发现在添加指令时发生错误，所以问题可能出在这里。 Angular version is: 角版本为：

"dependencies": {
"angular2": "2.0.0-beta.15"
}

<div class 'panel panel-primary'>

It should be 它应该是

<div class='panel panel-primary'>
