【问题描述】：

目前有一个问题，我收到错误“TypeError: Cannot read property of 'execute' of undefined”。我目前正在学习 Javascript，并从测试视频中复制了代码的 pastebin，似乎连他的代码都无法在我的编译器上运行。

index.js

const fs = require('fs');
const Discord = require('discord.js');
const bot = new Discord.Client({ partials: ["MESSAGE", "CHANNEL", "REACTION" ]});
const { prefix, token } = require('./config.json');

bot.commands = new Discord.Collection();

//File Reading
const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
for (const file of commandFiles) {
    const command = require(`./commands/${file}`);

    bot.commands.set(command.name, command);
}

//Command Callbacks
bot.on('message', message => {

    if (!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();
    if (command === 'queue') {
        bot.commands.get('queue').execute(message, args, Discord, bot);
    }
})

//Bot is Running
bot.once('ready', () => {
    console.log('Good Noodle Bot is online!');
});

//Login
bot.login(token);

queue.js

module.exports = {
    name: 'queue',
    description: "Begins a Competitive Queue",
    async execute(message, args, Discord, bot) {
        const channel = '802325198191067146';

        const silverRank = ':silver:803746337468186665';
        const novaRank = ':nova:803746340009279538';

        let embed = new Discord.MessageEmbed()
            .setColor('#e42643')
            .setTitle('Choose a rank to play with!')
            .setDescription('Choosing a rank will begin a queue for that rank!\n\n'
                + `${silverRank} for Silver\n`,
                + `${novaRank} for Nova`);

        let messageEmbed = await message.channel.send(embed);
        messageEmbed.react(silverRank);
        messageEmbed.react(novaRank);
    }
}

错误：

【问题讨论】：

打印出commandFiles变量的值。

【解决方案1】：

我错误地将命令放在另一个子文件夹 (commands/folder/command.js) 中
