ionic2 RC.0, Interface does not export

[masatada]

1.Make interface .ts file. (./src/app/test.ts)

export interface Test {
  id: number;
}

2.Import interface on app.component.ts.

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

import { Platform } from 'ionic-angular';
import { StatusBar } from 'ionic-native';

import { TabsPage } from '../pages/tabs/tabs';
import { Test } from './test';

@Component({
  template: `<ion-nav [root]="rootPage"></ion-nav>`
})
export class MyApp {

  // interface call 
  @Input() test: Test;

  rootPage = TabsPage;

  constructor(platform: Platform) {
    platform.ready().then(() => {
      StatusBar.styleDefault();
    });
  }
}

3.run ionic serve, it gives me an error:

[18:39:34]  bundle dev failed:  Module /Users/test/Documents/develop/unk/src/app/test.ts does not export Test (imported by /Users/test/Documents/develop/unk/src/app/app.component.ts)

[Manduro]

This is probably the same problem as this one: ionic-team/ionic-app-scripts#105. Interesting to see you traced it to the @Input typing!

Hello all! Thanks for opening an issue with us! I am going to go ahead and close this as a duplicate to the issue @Manduro linked to in the above comment as it does seem to be the same issue, or at least caused by the same root issue.
