链接两个Firebase身份验证方法给我错误-javascript

Question

I am trying to link email,password Auth method to current PhoneAuth method.

But it's giving me an error:

Cannot read property 'link' of undefined

Here is code:

import { firebaseAuth,fire,  messaging } from '../../config/constants';

var credential = fire.auth.EmailAuthProvider.credential(email, password);
fire.auth.currentUser.link(credential).then(function(user) {
  console.log("Account linking success", user);
}, function(error) {
  console.log("Account linking error", error);
});

And in config/constants

import firebase from 'firebase'
require("firebase/firestore");
const config = {
  apiKey: "AIzxxxxxxxxxxxxxxxxxxKXI",
    authDomain: "payxxxxxxxxxxxxja1.firebaseapp.com",
    databaseURL: "https://payxxxxxxxxxxja1.firebaseio.com",
    projectId: "payxxxxxxxxxxxxja1",
    storageBucket: "payxxxxxxxxxxxja1.appspot.com",
    messagingSenderId: "281xxxxx5xxxxx6"
}

firebase.initializeApp(config)

export const fire = firebase
export const ref = firebase.database().ref()
export const firebaseAuth = firebase.auth
export const messaging = firebase.messaging();

Please help me through this. Thanks

Following is what they have mentioned in there Docs.

Pass the AuthCredential object to the signed-in user's linkWithCredential method:

auth.currentUser.link(credential).then(function(user) {
  console.log("Account linking success", user);
}, function(error) {
  console.log("Account linking error", error);
});

And following is what resolves the problem.

auth.currentUser.linkWithCredential(credential).then(function(user) {
  console.log("Account linking success", user);
}, function(error) {
  console.log("Account linking error", error);
});

Simply replacing link with linkWithCredential made it working. That is how dumb the Doc writer is.
