Tengo un problema con base de fuego. Recibo este error: Uncaught TypeError: Failed to resolve module specifier "firebase/app". Relative references must start with either "/", "./", or "../". aplicación.js:

 import * as firebase from 'firebase/app'; import { Menu } from './Menu.js'; import { UserManagment } from './UserManagment.js'; const firebaseConfig = { apiKey: '[apiKey]', authDomain: '[authDomain]', projectId: '[projectId]', storageBucket: '[storageBucket]', messagingSenderId: '[messagingSenderId]', appId: '[appId]', measurementId: '[measurementId]', }; const app = firebase.initializeApp(firebaseConfig);

En el objeto firebaseConfig hay propiedades válidas copiadas del sitio de firebase. Instalé firebase por npm.
