Ionic cloud Auth No provider

Trying to use ionic-cloud’s auth module, I get this error

: No provider for Auth!

My page simply looks like

login(){
      this.auth.login('google').then(
          ()=>{
              console.log("Hello");
          }
      );

  }

Bump! Getting the same issue.

Have you added this Auth to your AppModule's providers array?

Yes, that results in
deps is undefined

You need to setup your project before using it. http://docs.ionic.io/setup.html

@NgModule({
  declarations: [ ... ],
  imports: [
    IonicModule.forRoot(MyApp),
    CloudModule.forRoot(cloudSettings)
  ],
  bootstrap: [IonicApp],
  entryComponents: [ ... ],
  providers: [ ... ]
})

registers the provider.
