代码如下 我有一个简单的不和谐机器人，并在事件下添加了一条消息文件--公会

    module.exports = (Discord, client, message) => {
    const prefix = '!';
    if(!message.content.startsWith(prefix) || message.author.bot) return;

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

    const command = client.commands.get(cmd);

    if(command) commmand.execute(client, message, args, Discord);
 }

```
Just Incase You need it here is my main file
```
const Discord = require('discord.js');
const client = new Discord.Client();
client.commands = new Discord.Collection();
client.events = new Discord.Collection();


['command_handler', 'event_handler'].forEach(handler =>{;
    require(`./handlers/${handler}`)(client, Discord)
})

 

 
client.login('My Token');

full error below

关于：这个不和谐机器人是一个简单的机器人，我正在尝试使用命令和事件处理程序来做，因为我是 discord js 而不是 javascript 的新手，我试图看看是否有一些问题，但找不到任何问题。调试窗口也无济于事，因为它是一个值/变量，显示为未定义，但在上面定义。因为我有点新，所以我使用了教程：https://www.youtube.com/watch?v=Sihf7B8D4Y8 并多次重写了代码。如果您有想法，请在我再次重写之前告诉我。
