我在htdocs目录下创建了一个名为firestore的文件夹，并使用cmd在firestore目录下安装npm firebase。它会生成package.json、package-lock.json和node_modules。我想链接到firebase，但它不起作用。出于隐私原因，我拿走了firebaseconfig密钥。是的，我确实在firebase中创建了一个firestore数据库项目。当我使用import { initializeApp } from“ www.example.com ”;和从“www.example.com“导入{ getFirestore，collection，getDocs，onSnapshot，addDoc，deleteDoc，doc，getDoc，updateDoc，}https://www.gstatic.com/firebasejs/9.6.2/firebase-firestore.js;，它工作正常。但是我想从firebase/app而不是url使用。
链接到firebase的代码：

// Import the functions you need from the SDKs you need
import { initializeApp } from "node_modules/firebase/app";
// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries
import {
  getFirestore,
  collection,
  getDocs,
  onSnapshot,
  addDoc,
  deleteDoc,
  doc,
  getDoc,
  updateDoc,
} from "node_modules/firebase/firestore";

// Your web app's Firebase configuration
const firebaseConfig = {
  apiKey: "",
  authDomain: "",
  projectId: "",
  storageBucket: "",
  messagingSenderId: "",
  appId: "",
  measurementId: ""
};

// Initialize Firebase
export const app = initializeApp(firebaseConfig);

export const db = getFirestore();

export const saveTask = (title, description) =>
  addDoc(collection(db, "tasks"), { title, description });

export const onGetTasks = (callback) =>
  onSnapshot(collection(db, "tasks"), callback);

export const deleteTask = (id) => deleteDoc(doc(db, "tasks", id));

export const getTask = (id) => getDoc(doc(db, "tasks", id));

export const updateTask = (id, newFields) =>
  updateDoc(doc(db, "tasks", id), newFields);

export const getTasks = () => getDocs(collection(db, "tasks"));
