node.js – firebase.intializeApp不是一个函数

所以我坚持这个错误.我正在用电报bot api制作一个电报机器人,现在我试图设置一个firebae数据库来保存一个组成员的分数 – 所以在重新启动机器人后不会重置分数.谁能告诉我问题是什么？我在这里阅读了许多类似的问题,但这些答案都没有解决我的问题. @H_696_2@bot.js

var TelegramBot = require('node-telegram-bot-api');
var firebase = require('firebase');

var token = 'myToken';
// Setup polling way
var bot = new TelegramBot(token,{polling: truE});

var app = firebase.intializeApp({
  serviceAccount: "C:/Mayer/scorebot/telegramscorebot.json",databaseURL: "https://blazing-heat-2008.firebaseio.com/"
});


/* function Person(name,score) {
this.name = name;
this.score = score;
}

var member = new Array();
member[0] = new Person("name1",0);
member[1] = new Person("name2",0);
member[2] = new Person("name3",0);
member[3] = new Person("name4",0);
member[4] = new Person("name5",0); */

bot.ontext(/\/echo (.+)/,function (msg,match) {
  var fromId = msg.from.id;
  if (match[1] == 'test') {
  var resp = match[1];
  bot.sendmessage(fromId,resp); }
  else {
  bot.sendmessage(fromId,'error!!');}
});

bot.ontext(/\/Vote (.+)/,match) {
  var fromId = msg.from.id;

for (var i = 0; i <= 4; i++) {
    if(member[i].name == match[1]){
        member[i].score += 1;
        bot.sendmessage(fromId,member[i].name + ' hat einen score von ' +         member[i].score);}
}
});
