node.js - 我想在不和谐机器人中获取成员计数，但它给出了错误

Question

我想在不和谐机器人中获取成员计数，但它给出了错误。我通过互联网搜索这个，但没有找到!这是代码:

const Commando = require('discord.js-commando');
const bot = new Commando.Client({commandPrefix: '$'});
const TOKEN = 'here is token';
const MIN_INTERVAL = 3 * 1000;
const guild = bot.guilds.get("394805546450026496");

bot.registry.registerGroup('connectc', 'Connectc');
bot.registry.registerGroup('defaultc', 'Defaultc');
bot.registry.registerDefaults();
bot.registry.registerCommandsIn(__dirname + "/commands")

bot.on('ready', function(){
    console.log("Ready");
    setInterval(function(){
        var memberCount = guild.members.filter(member => !member.user.bot).size;
        var memberCountChannel = bot.channels.get("547805078787194891");
        memberCountChannel.setName("👤Osoby: "+ memberCount +" 👤");
    }, MIN_INTERVAL);
});
bot.login(TOKEN);

这里出现错误:

C:\Users\User\Documents\Visual Studio Code\Discord Bots\VblacqeBot\index.js:18
    var memberCount = guild.members.filter(member => !member.user.bot).size;
                            ^

请帮助我!

根据您的错误结果，公会未定义。我运行了代码，它按预期工作。

module.exports.run = async (client, message, arguments) => {
   const guild = client.guilds.get("566596189827629066");
   setInterval(function () {
      var memberCount = guild.members.filter(member => !member.user.bot).size;  
      var memberCountChannel = client.channels.get("626462657817477131");
      memberCountChannel.setName(`${guild.name} has ${memberCount} members!`);
   }, 1000);
};

请仔细检查 394805546450026496 是否是有效的公会 ID，而不是 channel ID/用户 ID。如果是，请检查该机器人是否在上述公会中。

另一件事，建议在执行操作或从中读取数据之前查看公会是否可用。您可以通过 guild.available 进行检查.
