Angular2中的所有组件都必须引用视图中显示的其他组件.

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 {
