Javascript TypeError:undefined不是登录到steam时的函数

我正在从事steam项目。为此，我使用节点蒸汽模块。我对登录部分很感兴趣。 我在尝试使用节点steam登录steam帐户时遇到此异常 例外情况如下：

Uncaught TypeError: undefined is not a function   MYAPP/node_modules/adm-zip/zipFile.js:8

at TCP.close (net.js:457:12)

我的源代码如下：

var fs = require('fs');
var Steam = require('steam');
var crypto = require('crypto');

var serverlist = [] //server list here
Steam.servers = serverlist;

var steamClient = new Steam.SteamClient();
var steamUser = new Steam.SteamUser(steamClient);

steamClient.connect();

steamUser.on('updateMachineAuth', function (sentry, callback) {
    console.log('writing to file sentry');
    fs.writeFileSync('sentry', sentry.bytes);
    callback({ sha_file: getSHA1(sentry.bytes) });
});

function getSHA1(bytes) {
    var shasum = crypto.createHash('sha1');
    shasum.end(bytes);
    return shasum.read();
}

steamClient.on('connected', function () {    
    steamUser.logOn({
        account_name: “XXXXXXXX”,
        password: “XXXXXXXX”,
        // un-comment this when providing secondary auth-code from email
        auth_code: ‘XXX’,
        sha_sentryfile: getSHA1(fs.readFileSync('sentry'))
    });
});

steamUser.on('loggedOn', function () {
    console.log('Logged in!');
});


steamClient.on('debug', function (response) {
    console.log("debug: " + response);
});

steamClient.on('logOnResponse', function (response) {
    console.log(">>logOnResponse");
    console.log(response);

if (response.eresult == Steam.EResult.OK) {
    console.log('Logged in!');
    // Your code here
}

});

steamClient.on('error', function (error) {
    console.log(error.stack);
    alert("yes error");
});

steamClient.on('servers', function (servers) {
    alert(servers);
    // fs.writeFile('servers', JSON.stringify(servers));
});

steamClient.on('disconnected', function (s) {
    alert(s);
});

下面是我安装的版本

节点版本：v10.8.0 NPM版本：6.4.1 Steam版本：1.4.0 操作系统：Mac

请帮助我解决此问题。

正在发生的错误是，

未定义不是函数，因为您正在调用
节点中的函数
警报

这是无效的，因为在node中没有这样调用的函数，并且由于在
errorHandler
中也有该函数，因此应用程序死亡

如果要删除If的函数
alert
，并删除将
console.log（）
发生什么的“alert”函数，则错误应消失

尝试将此函数添加到代码中或删除所有警报函数：

const alert = () => {
  console.log(arguments)
}

你能证实我的回答吗？
