Can't resolve '@nativescript/core/utils'

First time using this plugin, I followed the guidelines and can't get it to run :
in my map.ts component :

import { Component, OnInit } from '@angular/core';

import { registerElement } from "nativescript-angular/element-registry";
registerElement("Mapbox", () => require("@nativescript-community/ui-mapbox").MapboxView);

@Component({
	moduleId: module.id,
	selector: 'garages-map',
	templateUrl: './garages-map.component.html',
	styleUrls: ['./garages-map.component.css']
})

export class GaragesMapComponent implements OnInit {

	constructor() { }

	ngOnInit() { }

}

my map.html

<ContentView height="100%" width="100%">
    <Mapbox
        accessToken="my secret key here"
        mapStyle="traffic_day"
        latitude="50.467735"
        longitude="13.427718"
        hideCompass="true"
        zoomLevel="18"
        showUserLocation="false"
        disableZoom="false"
        disableRotation="false"
        disableScroll="false"
        disableTilt="false"
        (mapReady)="onMapReady($event)">
    </Mapbox>
  </ContentView>

and when i run I have this exception :

I am testing on android

Start with package.json and the failing imports in node_modules/@nativescript-community/ui-mapbox/mapbox.js and mapbox.android.js. Compare the declared NativeScript, Angular, and ui-mapbox versions, then run the Android webpack build; done means the unresolved @nativescript/core/utils errors are gone and the map component builds.
