Question

Estoy tratando de integrar ng bootstrap UI en mi proyecto Angular 2. Después de seguir las sencillas instrucciones que se encuentran aquí: https://ng-bootstrap.github.io/#/getting-started obtengo el siguiente error al usar cualquier etiqueta de arranque de ngb:

Error: ¡Ningún proveedor para NgbAlertConfig!

import { BrowserModule } from ''@angular/platform-browser'';
import { NgModule } from ''@angular/core'';
import { FormsModule } from ''@angular/forms'';

import { NgbModule } from ''@ng-bootstrap/ng-bootstrap'';


@NgModule({

@Component({

Answer 1

Para cualquier otra persona que esté recibiendo este error para un componente diferente, por ejemplo, ngbDropdown ... asegúrese de tener el conjunto ngbDropdown en el elemento principal.

Answer 2

importa NgbModule en tu app.module.ts como este-

import {NgbModule} from ''@ng-bootstrap/ng-bootstrap'';

y agregarlo en la sección de importaciones de ngmodule-

@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

A ver si esto ayuda.
