javascript - 类型错误 : undefined is not a function while logOn to steam

Question

我正在开发 Steam 项目。为此，我正在使用 node-steam 模块。我在登录部分。我在尝试使用 node-steam 登录 Steam 帐户时遇到此异常异常如下:

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

at emitOne (events.js:75:13)
at Connection.emit (events.js:150:7)
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);
});

以下是我安装的版本。

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

请帮我解决这个问题。

Answer 1

正在产生的错误，undefined is not a function 正在发生，因为您正在 node 中调用函数 alert

那是无效的，因为在 Node 中没有这样调用的函数，并且由于您在 errorHandler 中也有该函数，因此应用程序终止。

如果您要删除函数 alert 如果您创建了 console.log() 正在发生的错误应该消失的“警报”函数。

尝试将此函数添加到您的代码或删除所有警报函数:

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