javascript - TypeError : firebase. auth(...).onAuthStateChanged 不是函数

Question

我正在尝试使用 onAuthStateChanged 触发器，但在使用“firebase deploy”时出现“不是函数”。 执行时:

firebase deploy

我收到以下错误:

Error: Error occurred while parsing your function triggers.
TypeError: firebase.auth(...).onAuthStateChanged is not a function

我还尝试了 firebase.default.auth.onAuthStateChanged，正如 Joao Lopes 在 this question 中发布的解决方案中提到的那样但它给出了同样的错误!

我正在使用:Ubuntu 16.04、npm 5.6.0、Firebase Spark。 这是我的 package.json:

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "serve": "firebase serve --only functions",
    "shell": "firebase experimental:functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "dependencies": {
    "consolidate": "^0.15.0",
    "express": "^4.16.2",
    "firebase-admin": "^5.8.2",
    "firebase-functions": "^0.8.1",
    "handlebars": "^4.0.11"
  },
  "private": true
}

和我的 index.js:

const functions = require('firebase-functions');
const firebase=require('firebase-admin');
const express=require('express');
const engines=require('consolidate'); 

firebase.initializeApp(functions.config().firebase);


const app=express();
app.engine('hbs',engines.handlebars);
app.set('views','./views');
app.set('view engine','hbs');

app.get('/',(req,res)=>{
    res.render('index',{Loginsignup:"LoginSignup"});
});

/*Here is the probleme*/
firebase.auth().onAuthStateChanged(function(user) {
     user.sendEmailVerification();
     if(!auth.currentUser.emailVerified){
         user.sendEmailVerification();
         console.log('signed in');
     }
});
/********************/

exports.app = functions.https.onRequest(app);

那我错过了什么？

firebase-admin SDK 中没有onAuthStateChanged 函数。此功能仅在客户端包中可用。
