【问题描述】：
如果认为我问的是愚蠢的，请不要发表评论。 我对此完全陌生。我尝试搜索解决方案，但找不到有用的解决方案或 discord.js 中的菜鸟可以理解的解决方案。提前感谢您的帮助！
const express = require ("express")
var app = require('express')();
app.get("/", (req, res) => {
res.send("hello hell!")
})
app.listen(3000, () => {
console.log("Project is ready")
})
let Discord = require("discord.js")
let client = new Discord.Client()
client.on('voiceStateUpdate', (oldVoiceState, newVoiceState) => {
let newUserChannel = newVoiceState.voiceChannel
let oldUserChannel = oldVoiceState.voiceChannel
if(oldUserChannel === undefined && newUserChannel !== undefined) {
// User Joins a voice channel
console.log(client.voiceConnections.size)
} else if(newUserChannel === undefined){
// User leaves a voice channel
console.log(client.voiceConnections.size)
}
})
client.login("token")
repl.it 某人加入时的结果 项目准备就绪
console.log(client.voiceConnections.size)

【问题讨论】：
-
错误告诉您
voiceConnections未定义。换句话说，那里没有可以请求size属性的对象。如果您有一个可能未定义的变量，那么您必须在使用它之前对其进行测试。 -
我该如何定义它？
-
这个问题显示了在使用 API 时东西从何而来的根本困惑。我会先阅读documentation。不知道您使用的是什么版本，但快速搜索文档表明
voiceConnections已弃用。也许这就是这里的问题。 -
版本是 12.5.1 我查看了文档，新命令应该是 guild.voice.connection;并且该语音连接现在是语音状态。虽然找不到任何关于 voiceconnections.size 的信息，所以我相信这从基础上讲是对的吗？。
-
从更改列表中：“
client.voiceConnections已被删除，现在位于ClientVoiceManager类中。此外，Collection不再是 getter。” i> 接下来是使用client.voice.connections而不是client.voiceConnections的建议——(link)
