我正在尝试将我的事件重做到 fs 事件系统中，以便为每个事件提供单独的文件，并且在将代码转换为 Discord.JS v12 时遇到了一些问题。

有人可以帮我弄清楚我的message.js文件出了什么问题吗？

这是我的代码：

index.js

const { Client } = require('discord.js-commando');
const path = require('path');
const fs = require('fs');
const server_invite = (process.env.INVITE_URL);
const owner_id = (process.env.BOT_OWNER);
const prefix = (process.env.BOT_PREFIX);
const stripIndents = require('common-tags').stripIndents;
require('dotenv').config();
const client = new Client({
    commandPrefix: prefix,
    unknownCommandResponse: false,
    disableMentions: 'everyone',
    owner: owner_id,
    invite: server_invite
})

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

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


fs.readdir('./events/', (err, files) => {
    if (err) return console.error;
    files.forEach(file => {
        if (!file.endsWith('.js')) return;
        const evt = require(`./events/${file}`);
        let evtName = file.split('.')[0];
        console.log(`Loaded event '${evtName}'`);
        client.on(evtName, evt.bind(null, client));
    });
});

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

message.js

const discord = require("discord.js");
const dotenv = require('dotenv').config;
const prefix = (process.env.BOT_PREFIX);
const fs = require('fs');

module.exports = (client, message) => {
    if (message.author.bot) return;
    if (message.content.indexOf(prefix) !== 0) return;

    const args = message.content.slice(prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    const cmd = client.commands.cache.get(command);
    if (!cmd) return;

    cmd.run(client, message, args);
};

基本上每次我运行命令时都会使机器人崩溃。除此之外，我的ready.js活动似乎完美无缺。

这是我的message.js文件抛出的错误：

/app/events/message.js:13
    const cmd = client.commands.cache.get(command);
                              ^

我正在跑步Discord.JS ^12.0.0，如果有帮助discord.js-commando discord.js/Commando的话。node ^12.16.4

感谢所有回复的人的帮助。能够message.js使用提供的响应修复我的文件。

message.js如果有人想使用它，这是我的工作文件：

const client = require('discord.js-commando');
const prefix = (process.env.BOT_PREFIX);
require('dotenv').config;

module.exports = (message) => {

    if (message.author.client) return;
    if (message.content.indexOf(prefix) !== 0) return;


    const args = message.content.slice(prefix.length).trim().split(/ +/g);
    const command = args.shift().toLowerCase();

    const cmd = client.commands.cache.get(command);
    if (!cmd) return;

    cmd.run(client, message, args);
};

因为您使用的是 Commando，所以您不需要另一个侦听器来监听该message事件。图书馆已经为您做到了。删除message.js应该会删除错误。

发生错误是client.commands因为 undefined. 您似乎正在使用主要指南中的代码，该代码适用于不使用 Commando 的机器人，并假定您已经设置client.commands了Collection您的命令。您可能想看看突击队指南。

请不要在一篇文章中提出多个问题。如果您对其他事件处理程序有不同的问题，请提出一个新问题。
