我想在我的机器人中使用不和谐成员计数命令，但它给了我一个错误

Question

这是 discord.js v13 membercount 命令。由于某种原因它不起作用。我在许多不和谐的服务器上寻求帮助，但他们视而不见。如果有人可以提供帮助，那就太棒了。

const Discord = require("discord.js");
const {MessageEmbed} = require("discord.js");
const config = require("../../botconfig/config.json")
var ee = require("../../botconfig/embed.json")
const settings = require("../../botconfig/settings.json");
module.exports = {

  argstoomany_message: "", //Message if the user has too many / not enough args / too many plus args, which will be sent, leave emtpy / dont add, if you wanna use command.usage or the default message! [OPTIONAL]
  run: async (client, message, args, plusArgs, cmdUser, text, prefix) => {
    try {
      await message.guild.members.fetch();
        message.reply({embeds: [new Discord.MessageEmbed()
        .setAuthor("Member-Count Information About: " +  message.guild.name, message.guild.iconURL({
          dynamic: true
        }),)
        .setColor(ee.color)
        .addField("❱ Total USERS", "???? \`" + message.guild.memberCount + "\`", true)
        .addField("❱ Total HUMANS", "???? \`" + message.guild.members.cache.filter(member => !member.user.bot).size + "\`", true)

        .addField("❱ IDLE", "???? \`" + message.guild.members.cache.filter(member => !member.user.bot && member.presence.status == "idle").size + "\`", true)
        .addField("❱ IDLE", "???? \`" + message.guild.members.cache.filter(member => member.user.bot && member.presence.status == "idle").size + "\`", true)

        .addField("❱ DND", "???? \`" + message.guild.members.cache.filter(member => !member.user.bot && member.presence.status == "dnd").size + "\`", true)
        .addField("❱ DND", "???? \`" + message.guild.members.cache.filter(member => member.user.bot && member.presence.status == "dnd").size + "\`", true)
        
        .addField("❱ OFFLINE", ":black_circle:\`" + message.guild.members.cache.filter(member => member.presence.status == "offline").size + "\`", true)
        .addField("❱ OFFLINE", ":black_circle:\`" + message.guild.members.cache.filter(member => !member.user.bot && member.presence.status == "offline").size + "\`", true)
        .addField("❱ OFFLINE", ":black_circle:\`" + message.guild.members.cache.filter(member => member.user.bot && member.presence.status == "offline").size + "\`", true)
        .setTimestamp()
      ]});
    } catch (e) {
      console.log(String(e.stack).bgRed)
      return message.reply({embeds: [new MessageEmbed()
          .setColor(ee.wrongcolor)
          .setFooter(ee.footertext, ee.footericon)
          .setTitle(`❌ ERROR | An error occurred`)
          .setDescription(`\`\`\`${e.message ? String(e.message).substr(0, 2000) : String(e).substr(0, 2000)}\`\`\``)
      ]});
    }
  }
}

这是错误

我应该添加更多细节。您不需要阅读此内容，它只是不断要求我添加越来越多的细节。

Answer 1

注意：此代码是为 Discord.js v13.3.1 编写的

---

过滤空值

正如@ceejayoz 所指出的，Member#presence 是未定义的。当用户离线时会发生这种情况，因为如果您离线，您就没有活动状态。你的存在是空的。 （改编自@Elitezen 的评论）。一个简单的解决方案是通过删除 Presence 为空的任何成员来过滤您正在获取的列表。它看起来像这样：

<GuildMemberManager>.cache.filter(m => m.presence != null)

现在，我已将 GuildMemberManager 放入 。这意味着您可以用 GuildMemberManager 替换它。为了您的使用，您可以将其替换为

message.guild.members

但是，你可以简单地这样声明。

多用途

我还注意到您使用类似的代码一遍又一遍地重复相同的行。我所指的部分是 GuildMemberManager。您可以通过在开头声明一个变量并在需要 GuildMemberManager 时重用它来简化代码，您可以引用该变量。这是您可以做的一个示例。你必须使用 await 因为这个函数是基于 Promise 的。

const manager = await message.guild.members.fetch()

此外，在代码的顶部，您两次使用 require 函数来导入两个对象。您导入整个 Discord 对象，然后导入 MessageEmbed 对象。这可以通过删除第一行轻松减少。

const { MessageEmbed } = require(`discord.js`)

在第 25 行，您将代码从 Discord.MessageEmbed 更新为 MessageEmbed。您还可以通过使用.addFields(...) 来简单地编写更多代码，而不是一遍又一遍地重复运行.addField(...)。

结果代码

最后，通过我在这里展示的所有更改，这就是您的新代码的样子。 重要！ 您必须在调用管理器构造函数之前以及当它可以访问message 变量时放置它。定义 run 函数后的第 23 行可以很好地解决这个问题。

const { MessageEmbed } = require(`discord.js`);
// ...
const manager = await message.guild.members.fetch()
.addFields(
  { name: `❱ Total USERS`, value: `? \`${message.guild.memberCount}\``, inline: true },
  { name: `❱ Total HUMANS`, value: `? \`${manager.filter(m => !m.user.bot).size}\``, inline: true },
  { name: `❱ Total BOTS`, value: `? \`${manager.filter(m => m.user.bot).size}\``, inline: true },
  { name: `❱ ONLINE`, value: `? \`${manager.filter(m => m.presence != null).size}\``, inline: true },
  { name: `❱ ONLINE`, value: `? \`${manager.filter(m => m.presence != null && !m.user.bot).size}\``, inline: true },
  { name: `❱ ONLINE`, value: `? \`${manager.filter(m => m.presence != null && m.user.bot).size}\``, inline: true },
  { name: `❱ IDLE`, value: `? \`${manager.filter(m => m.presence != null && m.presence.status === `idle`).size}\``, inline: true },
  { name: `❱ IDLE`, value: `? \`${manager.filter(m => m.presence != null && m.presence.status === `idle` && !m.user.bot).size}\``, inline: true },
  { name: `❱ IDLE`, value: `? \`${manager.filter(m => m.presence != null && m.presence.status === `idle` && m.user.bot).size}\``, inline: true },
  { name: `❱ DND`, value: `? \`${manager.filter(m => m.presence != null && m.presence.status === `dnd`).size}\``, inline: true },
  { name: `❱ DND`, value: `? \`${manager.filter(m => m.presence != null && m.presence.status === `dnd` && !m.user.bot).size}\``, inline: true },
  { name: `❱ DND`, value: `? \`${manager.filter(m => m.presence != null && m.presence.status === `dnd` && m.user.bot).size}\``, inline: true },
  { name: `❱ OFFLINE`, value: `:black_circle: \`${manager.filter(m => m.presence === null).size}\``, inline: true },
  { name: `❱ OFFLINE`, value: `:black_circle: \`${manager.filter(m => m.presence === null && !m.user.bot).size}\``, inline: true },
  { name: `❱ OFFLINE`, value: `:black_circle: \`${manager.filter(m => m.presence === null && m.user.bot).size}\``, inline: true }
