That solved the issue. Thank you!

I’m really struggling with integrating OnsenUI in my Angular 2 (version 4) App. The project was generated using the latest Angular CLI.

So if add in app.module.ts

import {OnsenModule} from 'angular2-onsenui';
import {CUSTOM_ELEMENTS_SCHEMA} from '@angular/core';
.
.
.
@NgModule({
imports: [
    OnsenModule,
    BrowserModule
],
schemas: [CUSTOM_ELEMENTS_SCHEMA]

as it is described in the docs: https://onsen.io/v2/docs/guide/angular2/

I’m getting the following error:

Uncaught ReferenceError: ons is not defined

I don’t want to use the monaca template, this will not solve the problem.
