Can't import directly NbCalendarWithTimeComponent

[pacocom]

When
import { NbCalendarWithTimeComponent } from '@nebular/theme/components/datepicker/calendar-with-time.component';
...
@ViewChild('startCalendar', { read: NbCalendarWithTimeComponent }) startCalendar!: NbCalendarWithTimeComponent<Date>;

appears the error:
datetime-picker-from-to.component.ts:5:0-112 - Error: Module not found: Error: Can't resolve '@nebular/theme/components/datepicker/calendar-with-time.component' in '/home/francisco-javier/solaire-framework/services/admin/src/app/shared/modules/datetime-picker-from-to'
