error TS2345: 
Argument of type '{ selector: string; template: string; directives: (typeof Title | any[])[]; providers: typeof Goo...' is not assignable to parameter of type 'ComponentMetadataType'.

这里是我的代码：

import { Component,Input } from "@angular/core";
import { Title } from "./components/title";
import { Timeline } from "./components/timeline";

@Component({
  selector: "edu",template: `
            <div id="Edu" class="Edu content section scrollspy">
              <title [icon]="titleIcon" [title]="titleTitle"></title>
              <timeline [data]="edu"></timeline>
            </div>
            `,directives: [Title,Timeline]
})

export class Edu {
  private titleIcon = "graduation-cap";
  private titleTitle = "Education";
  @Input("data") edu: Array<Object>;
}

我的代码中没有看到任何错误，也是以前的工作。任何人都可以看到有什么问题吗？

注意：我使用Angular2-rc6和TypeScript 1.8.10，希望这些信息有所帮助
