这是我的代码：

import * as firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';

// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
    apiKey: "AIzaSyCtaFhg2rHV7ZuPKFIMaisRsiNUhwSzez8",
    authDomain: "twitter-c8bcc.firebaseapp.com",
    projectId: "twitter-c8bcc",
    storageBucket: "twitter-c8bcc.appspot.com",
    messagingSenderId: "951402712179",
    appId: "1:951402712179:web:9fe473631359f6f3656e06",
    measurementId: "G-7QKS23B79V"
};
const firebaseApp = firebase.initializeApp(firebaseConfig);
  
const db = firebaseApp.firestore();

export default db;

当我安装npm install firebase/firestore时，它显示了这个错误：
