您好，我尝试为我的 discord 机器人创建一个命令处理程序，但是当我尝试我的 !ping 命令时，我总是收到错误消息

这是我的 main.js 文件

const Discord = require('discord.js')

const client = new Discord.Client()

const {TOKEN ,PREFIX} = require('./config')

const fs = require('fs')

client.commands = new Discord.Collection();

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

client.on('ready', () =>{
    console.log("I'm ready!!!")
})
  
client.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 == 'ping'){
     client.commands.get('ping').execute(message,args)
 }

});

client.login(TOKEN)

还有我的 ping.js 文件

module.export = {
    name: 'ping',
    description: "ping",
    execute(message, args){
    
    message.channel.send('pong')

    }

}

我遇到的错误

     client.commands.get('ping').execute(message,args)
                                ^

【解决方案1】：

使用module.exports，因为模块上不存在export属性（export需要复数）。
