TypeError: logOn to steam时，未定义不是函数

Question

我正在从事steam项目。为此，我使用node-steam模块。我在登录部分。当我尝试使用logOn - steam异常连接到steam帐户时，我得到了这个异常，如下所示：

Uncaught TypeError: undefined is not a function   MYAPP/node_modules/adm-zip/zipFile.js:8 
Module.exports  /MYAPP/node_modules/adm-zip/zipFile.js:8 
module.exports /MYAPP/node_modules/adm-zip/adm-zip.js:25

at emitOne (events.js:75:13)
at Connection.emit (events.js:150:7)
at TCP.close (net.js:457:12)

我的源码是添加如下：

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蒸汽版本: 1.4.0操作系统: Mac

请帮我解决这个问题。

由于您在node中调用函数alert，因此发生了正在产生的错误：undefined is not a function

这是无效的，因为在node中没有这样调用的函数，而且由于在errorHandler中也有该函数，因此应用程序将终止。

如果您要删除的函数警报，如果您创建和“警报”函数，将console.log()正在发生的事情，错误应该消失。

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)
}
