Angular2 中的所有组件都必须引用视图中出现的其他组件。

Ionic 似乎用他们自己的@Page注释来处理这个问题，但它只涵盖了 Ionic 特定的组件。decorators.ts解释了这种行为。

您需要编辑代码以包含OAuthComponent在directives：

@Page({
    templateUrl: 'app/getting-started/getting-started.html',
    directives: [OAuthComponent] // Don't forget to import it
})
export class GettingStartedPage {
