angular 2 - 在 TestComponent 上找不到指令注释

Question

Angular 版本 2.0.0-rc.4

test.component.ts

import {Component} from '@angular/core';

Component({
    selector: 'test',
    templateUrl: 'templates/test.tpl.html'
})

export class TestComponent{

}

我的组件.component.ts

import {Component} from "@angular/core";
import {OnInit} from "@angular/core";
import {TestComponent} from "./test.component";

@Component({
    selector: 'my-component',
    template: `
        I am <span [style.color]="inputElement.value === 'yes' ? 'red' : '' ">{{name}}</span>. 
        <br>
        <br>
        <span [class.it-awesome]="inputElement.value==='yes'">It awesome!</span>
        <input type="text" #inputElement (keyup)="0"/>
        <button [disabled]="inputElement.value !=='yes'">Only enabled if 'yes' was entered </button>
        <test></test>
    `,
    styleUrls: ['assets/scss/mycomponent.scss'],
    directives: [TestComponent]

})
export class MyComponentComponent implements OnInit {
    name: string;

    ngOnInit():any {
        this.name = "Dima";
    }
}

每次在控制台 google chrome 中显示错误:在 TestComponent 上找不到指令注释。为什么没有找到？文件名是 test.component.ts。

有一个拼写错误。在组件前添加一个@。

import {Component} from '@angular/core';

@Component({
    selector: 'test',
    templateUrl: 'templates/test.tpl.html'
})
export class TestComponent{

}
