Discord.JS-Commando Discord Bot 中的 TypeError

Question

好的，所以我有一个内置于 discord.js-commando 的机器人。我一直在对其进行一些调整，主要是尝试添加更多功能，例如按名称记录命令等到通道以及添加 console.error 日志记录。

现在我尝试获取通道日志记录在命令中可见，但是机器人不断抛出 TypeError.... 我不知道是什么导致了这个错误，也不知道如何修复它。

有人可以看看我的代码并帮助我找出导致 TypeError 的原因吗？

这是我不断收到的错误：

console.error

这是我的主要机器人文件：

index.js

const { Client } = require('discord.js-commando');
const { RichEmbed } = require('discord.js')
const path = require('path');
const prefix = (process.env.BOT_PREFIX);
const twitch_url = (process.env.TWITCH_URL);
const embed_color = (process.env.EMBED_COLOR);
const embed_img = (process.env.EMBED_IMG);
const embed_url = (process.env.EMBED_URL);
const avatar_url = (process.env.AVATAR_URL);
const thumbnail_url = (process.env.THUMBNAIL_URL);
const welcome_channel = (process.env.WELCOME_CHANNEL_NAME);
const member_role = (process.env._MEMBER_ROLE_NAME);
require('dotenv').config();
const client = new Client({
    commandPrefix: prefix
})

client.registry
    .registerDefaultTypes()
    .registerGroups([
        ['admin', 'Administration'],
        ['mod', 'Moderation'],
        ['fun', 'Fun'],
        ['misc', 'Miscellanious'],
        ['util', 'Utility']

    ])
    .registerDefaultGroups()
    .registerDefaultCommands()
    .registerCommandsIn(path.join(__dirname, 'commands'))

client.on('ready', () => {
    console.log(`Logged in as ${client.user.tag}(${client.user.id})`)
    client.user.setActivity(`${prefix}help`, {
        type: "STREAMING",
        url: twitch_url
    })
});

client.on("guildMemberAdd", (member) => {
    console.log(`New User "${member.user.username}" has joined "${member.guild.name}"`);
    guildMember.addRole(guildMember.guild.roles.find(role => role.name === member_role));


    let channel = member.guild.channels.find(c => c.name === welcome_channel);
    const embed = new RichEmbed()
        .setAuthor("Yuzuki Yukari", avatar_url)
        .setUrl(embed_url)
        .setColor(embed_color)
        .setImage(embed_img)
        .setThumbnail(thumbnail_url)
        .setFooter("Yuzuki Yukari", avatar_url)
        .addField("Welcome", `${member.user.username} has joined ${member.guild.name}`)
    return channel.send(embed).catch(console.error);
});

client.on('guildMemberRemove', (member) => {
    let channel = member.guild.channels.find(c => c.name === welcome_channel);
    const embed = new RichEmbed()
        .setAuthor("Yuzuki Yukari", avatar_url)
        .setUrl(embed_url)
        .setColor(embed_color)
        .setImage(embed_img)
        .setThumbnail(thumbnail_url)
        .setFooter("Yuzuki Yukari", avatar_url)
        .addField("Goodbye", `${member.user.username} has left ${member.guild.name}`)
    return channel.send(embed).catch(console.error);
});

client.on('error', console.error)
client.login(process.env.BOT_TOKEN);

这是我的 package.json 文件：

package.json

{
  "name": "yuzuki",
  "version": "1.0.0",
  "description": "A Discord Moderation Bot built using Discord.js commando",
  "main": "index.js",
  "scripts": {
    "start": "node index.js",
    "dev": "nodemon index.js"
  },
  "author": "Nimbi",
  "license": "ISC",
  "dependencies": {
    "discord.js": "^12.0.1",
    "discord.js-commando": "^0.10.0",
    "path": "^0.12.7",
    "snekfetch": "^4.0.4",
    "sqlite": "^4.0.14",
    "uws": "^100.0.1",
    "nodemon": "^1.13.3",
    "dotenv": "^8.2.0"
  },
  "engines": {
    "node": "^12.0.0"
  }
}

我的依赖项和它们的版本可以在我的package.json 中看到，但是我的 node.js 版本是^12.0.0，我的 discord.js 版本是^12.0.1，我的 discord.js-commando 版本是^0.10.0如果有帮助的话。

Answer 1

discord.js-commando@0.10.0 与 discord.js@12 不兼容。 package.json 指定必须使用 Discord.js ^11.2.0。

该错误是因为 Collection#filterArray 在 v12 中被删除，因此 this.commands.filterArray 是 undefined 而不是 Commando 代码中的函数。

你有两个选择：

1. 降级到 Discord.js v11。
2. 使用discord.js-commando 的master 分支，该分支与 Discord.js v12 兼容。但是，此分支可能不稳定和/或存在错误。
   要使用此功能，请将 package.json 中的 "discord.js-commando": "^0.10.0" 更改为 "discord.js-commando": "discordjs/Commando"。有关这方面的更多详细信息，请参阅 npm 的 package.json 文档中的 GitHub URLs。
