我收到错误TypeError无法读取未定义的属性“execute”

Question

我的主代码我正在尝试制作一个不和谐的机器人我得到了这个错误类型错误无法读取'execute'的属性未定义我有每一个解决方案，但它仍然有一些错误，如果有人解决它将不胜感激。我试图使一个简单的迪斯科机器人，但代码不仅工作请hlep。

const client = new Discord.Client();

const prefix = '-';

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.once('ready', () => {
    console.log('yes its online');
});


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();


 client.on('guildMemberAdd', member =>{
       const channel = member.guild.channels.cache.find(channel=> channel.name === "hlo");
       if(!channel) return;

       channel.send(`Welcome to our server , ${member}, please read the rules!`);

    });
    

    if(command === 'ping'){
        message.channel.send('pong!');
    }
    if (command == 'kick'){
       client.commands.get('kick').execute(message, args);
    }
    if (command === 'ban'){
        client.commands.get('ban').execute(message, args);
        }
    
}); ```

My ban code 
```module.exports = {
    name: 'ban',
    description: "Uses ban hammer",
    execute(messsage, args){

    
     if (command === "ban"){
        const userBan = message.mentions.users.first();

        if(userBan){
            var member = message.guild.member(userBan);

            if(member) {
                member.ban({
                    reason: 'you broke rules buddy.'
                }).then(() => {
                    message.reply(`${userBan.tag} was banned from the server.`)
                })

            } else{
                message.reply('that user is not in the server.');
            }
        }else {
            message.reply('you need to state a user to ban')
        }
}
}

我的踢码

module.exports = {
    name: 'kick',
    description: 'kick people',
    execute(messsage, args){

    
     if (command === "kick"){
        const userKick = message.mentions.users.first();

        if(userBan){
            var member = message.guild.member(userKick);

            if(member) {
                member.kick({
                    reason: 'you broke rules buddy.'
                }).then(() => {
                    message.reply(`${userKick.tag} was kicked from the server.`)
                })

            } else{
                message.reply('that user is not in the server.');
            }
        }else {
            message.reply('you need to state a user to kick')
        }
}
}```
