Did you try providing the service to relevant module where the service is used. Note the providers array

@NgModule({
  imports:      [ BrowserModule, FormsModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ],
  providers: [ScrollBarHelper]
})
export class AppModule { }

UPDATE: NgxDatatableModule

Try adding NgxDatatableModule import

@NgModule({
  imports:      [ BrowserModule, FormsModule, NgxDatatableModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ],
  providers: [ScrollBarHelper]
})
export class AppModule { }
