Answer 1

Since Ionic 2.2.0, it's recommended to use @ionic/storage version 2.0.0. Configuration in app.modules.ts has changed since the previous version. The error occurs if you haven't changed everything in the right way.

In app.modules.ts do following changes:

1. Remove Storage from providers

2. Change import statement:

   from: import { Storage } from '@ionic/storage';

   to: import { IonicStorageModule } from '@ionic/storage';

3. Add the following to the imports array:

   IonicStorageModule.forRoot()

The import array should look like below:

imports: [
  IonicModule.forRoot(MyApp),
  IonicStorageModule.forRoot()
],

NOTE: Do not make any change in imports of Storage in any other files.
