所以，我试图用discord.js创建一个bot，但遇到了一个我不知道如何解决的错误，我已经找了几个小时也找不到答案，当我运行bot时，它成功地登录了，但是当你运行一个命令时，powershell控制台抛出一个错误“typeerror:不能读取undefined的property'execute'”
这是我的主要代码
const Discord = require('discord.js');
const config = require('./config.json');
const client = new Discord.Client();
const { prefix, token } = require('./config.json');
const ms = require('ms');
const fs = require('fs');
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
client.once('ready', async () => {
console.log(`Logged in as ${client.user.tag}!`);
});
client.on('message', message => {
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).trim().split(/ +/);
const commandName = args.shift().toLowerCase();
const command = client.commands.get(commandName) || client.commands.find(cmd => cmd.aliases && cmd.aliases.includes(commandName));
try {
command.execute(message, args);
} catch (error) {
console.error(error);
message.reply('This command has an issue.')
}
// other commands...
});
client.login(token);
这是一个command.js文件，该命令旨在清除500-2范围内的x ammount消息
module.exports = {
name: "purge",
description: "Deletes input amout of messages.",
async execute(message, args) {
if (message.member.hasPermission(MANAGE_MESSAGES)) {
const deleteCount = parseInt(args[0], 10);
const deleteMessage = `Deleted ${deleteCount} messages.`;
if (!deleteCount || deleteCount > 500 || deleteCount < 2) return message.reply(`${message.author} please input a number between 2 - 500.`);
const fetched = await message.channel.fetchMessages({
limit: deleteCount
});
message.channel.bulkDelete(fetched)
.catch(err => console.log(`Cannot delete message because of ${err}`))
.then(message.reply(deleteMessage))
.catch(err => {
console.log(err);
})
} else {
message.reply('You do not have permissions to purge.')
}
}
}
错误消息为:
TypeError: Cannot read property 'execute' of undefined

如果有人能帮我的话我会非常感激的。
实际上，您并没有在commands集合中设置任何命令，因此任何获取命令的尝试都将返回未定义的命令。
// create the collection
client.commands = new Discord.Collection();
// get an array of every file in the commands folder
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));
// iterate a function through every file
for (file of commandFiles) {
const command = require(`./commands/${file}`);
// map the command to the collection with the key as the command name,
// and the value as the whole exported object
client.commands.set(command.name, command);
};
