Ionic2: Bundle failed: Could not resolve '../providers/data' from


Working with Ionic2 RC.1 and creating a fresh app using the tabs template.

The app works until I generate a provider. The moment I add it, I get the error

[16:40:11]  lint finished in 1.41 s 
[16:40:13]  transpile finished in 2.93 s 
[16:40:13]  bundle started ...

  quit or q to shutdown the server and exit

My app.module.ts

import { NgModule } from '@angular/core';
import { IonicApp, IonicModule } from 'ionic-angular';
import { MyApp } from './app.component';
import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { HomePage } from '../pages/home/home';
import { TabsPage } from '../pages/tabs/tabs';

import { Data } from '../providers/data';

  declarations: [
  imports: [
  bootstrap: [IonicApp],
  entryComponents: [
  providers: [Data]
export class AppModule {}

Any ideas ?


Apparently ionic couldn’t find your file.
Is it data.ts directly in the providers directory ?
Or data.ts in directory “data” in directory “providers” ?
What does your app structure looks like ?

Generally, you should have somtehing like that : import { Data } from '../../providers/data/data';


@elvis_gn If the path ../providers/data is a folder (with an index.ts file inside, exporting classes; that is, a barrel) you can try to import from ../providers/data/index. At least this is what happened to me when I updated from RC0 to RC1, and I had to change imports in hundreds of files T-T (the good thing is that it worked).

If this is not your case, maybe your path is wrong in app.module.ts, like @mvrc pointed out. Do you have the file /Users/.../src/providers/data.ts?


If your problem is with barrels (you have an index.ts file inside your folder), it is now fixed. Just update ionic-app-scripts to version 0.0.36:

npm install @ionic/app-scripts@latest --save-dev
