Angular2 - 收到错误 : `EXCEPTION: No Directive annotation found on MyComponent`

Question

当我尝试从其他文件导入指令时，出现错误，如 EXCEPTION: No Directive annotation found on MyComponent - 如何解决这个问题？

这是我的代码:

应用程序组件.ts:

import {Component} from 'angular2/core';
import {MyComponent} from "./app.my-component"

@Component({
    selector: 'app',
    template: `
        <h1>Hellow World</h1>
        <span>Here is your component:</span>
        <my-component></my-component>
    `,
    directives: [MyComponent]
})

export class AppComponent { }

app.mycomponent.ts:

import {Component} from 'angular2/core';

@Component({

    selector : 'my-component',

    template : `<h2>This is from My component</h2>`

});

export class MyComponent { };

但我收到错误消息:在 MyComponent 上找不到指令注释 如何解决这个问题？

您应该在组件关闭 Component 指令括号后删除 ;。

import {Component} from 'angular2/core';

@Component({

selector : 'my-component',

template : `<h2>This is from My component</h2>`

})
export class MyComponent { };
