Import Ionic2 component in Angular2 app

Ionic Framework ionic-v3
1

Hello,

Is it possible to use Ionic2 components only in an existing Angular2 application?

Currently, I have an ng2 app, with @angular2-material/* and ng2-material component.
I use webpack to build the application (a clone from https://github.com/AngularClass/angular2-webpack-starter)

I would like to use Ionic2 component (I know, I am loosing many great features provided by Ionic by doing only a ng2 app).

I tried a simple @Component .ts with

import { IONIC_DIRECTIVES } from 'ionic-angular';

and

    <ion-item>
        <ion-label>Gender</ion-label>
        <ion-select [(ngModel)]="gender">
            <ion-option value="f" checked="true">Female</ion-option>
            <ion-option value="m">Male</ion-option>
        </ion-select>
    </ion-item>

but I have the following error
ORIGINAL EXCEPTION: No provider for Form!

My app is bootstrap from angular2 bootstrap() not ionicBootstrap() and I did not add any ionic provider. Should I? What/How? What am I missing?
Does ion-select need to be in a form?
