Using Angular 4, am I missing something? The install didn't produce any errors.
Only using the basic example.

import {AngularOpenlayersModule} from 'angular2-openlayers';

@NgModule({
imports: [
BrowserModule,
AppRoutingModule,
FormsModule,
HttpModule,
BsDropdownModule.forRoot(),
TabsModule.forRoot(),
ChartsModule,
FormWizardModule,
AngularOpenlayersModule,
