Question

我正在尝试在react中初始化多个firebase项目，但出现一个奇怪的错误，提示× `Firebase：名为'[DEFAULT]'的Firebase应用已存在（app / duplicate-app）。

我`选择了一个完全不同的字符串，但是仍然无法正常工作。有人可以解释我在做什么错吗？谢谢您的帮助！

reference.js

import * as firebase from "firebase";



  var config = {
    apiKey: "AIzaSyDsTsClk8l2l5yLNu_eG-R06Usv4Oi_NvQ",
    authDomain: "d-ucukgx.firebaseapp.com",
    databaseURL: "https://d-ucukgx.firebaseio.com",
    projectId: "d-ucukgx",
    storageBucket: "d-ucukgx.appspot.com",
    messagingSenderId: "1031835936266"
  };
  firebase.initializeApp(config);



  const databaseRef = firebase.database().ref();
export const ChampsRef = databaseRef.child("Champs");


export const authRef = firebase.auth();
export const timeRef = firebase.database.ServerValue.TIMESTAMP;

export default databaseRef;

config / dev.js

import * as firebase from "firebase";



  var firebaseConfig2 = {
    apiKey: "AIzaSyDsTsClk8l2l5yLNu_eG-R06Usv4Oi_NvQ",
    authDomain: "d-ucukgx.firebaseapp.com",
    databaseURL: "https://d-ucukgx.firebaseio.com",
    projectId: "d-ucukgx",
    storageBucket: "d-ucukgx.appspot.com",
    messagingSenderId: "1031835936266"
  };
  firebase.initializeApp(firebaseConfig2);




var app = firebase.initializeApp(firebaseConfig2, "auth");
export default app;

您不能将相同的配置用于2 intializeApp，只需对其初始化一次，然后导出您的app

您必须在配置后给第二个firebase.initializeApp(firebaseConfig2)命名。所以看起来像这样。

firebase.initializeApp(firebaseConfig2, 'secondary');
