错误：部署谷歌云功能时找不到模块“firebase/app”

Question

基本上，我试图让一个 firebase 函数简单地在文档中输出值，我只是在本地实现了这一点……但该函数不会部署到云端。下面是函数

const functions = require('firebase-functions');
const firebase = require('firebase/app');
require('firebase/firestore');

const firebaseConfig = {
    projectId: "covid-info-bw"
};

const db = firebase
.initializeApp(firebaseConfig)
.firestore()

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
exports.helloWorld = functions.https.onRequest((request, response) => {
  response.send("Hello from Firebase! Dawg I am beast");
});


exports.getData = functions.https.onRequest((req, res) => {
const docRef = db.collection('FunctionTest').doc('Cm38kBYShNnyuLVpizcy');
const getDoc = docRef.get()
    .then(doc => {
    if (!doc.exists) {
        console.log('No such document!');
        return res.send('Not Found')
    } 
        console.log(doc.data());
        return res.send(doc.data());
    })
    .catch(err => {
    console.log('Error getting document', err);
});

这是来自 package.json 的 sn-p

"dependencies": {
  "@firebase/app": "^0.6.1",
  "@firebase/firestore": "^1.14.0",
  "@google-cloud/firestore": "^3.7.4",
  "firebase-admin": "^8.10.0",
 "firebase-functions": "^3.6.0"
},

这是我运行“firebase deploy --only functions:getData,functions:helloWorld”时遇到的错误

λ firebase deploy --only functions:getData,functions:helloWorld

 Did you list all required modules in the package.json dependencies?

 Functions deploy had errors with the following functions:
        getData
        helloWorld


 To try redeploying those functions, run:
     firebase deploy --only functions:getData,functions:helloWorld


 To continue deploying other features (such as database), run:
     firebase deploy --except functions

Error: Functions did not deploy properly.

您不应该将 Firebase 客户端 SDK 用于后端代码。您尝试执行的操作只能使用 Google Cloud Firestore SDK (@google-cloud/firestore) 或 Firebase Admin SDK (firebase-admin，它只编写 Cloud SDK) 来实现。只需删除 Firebase 客户端 SDK（以 @firebase 开头）并仅使用您喜欢的后端 SDK。
