【问题描述】：

我想尝试一个命令处理程序，但我有一个错误。 如果我运行,ping 机器人是响应，但如果我运行, 我得到一个错误，这是日志：

TypeError: Cannot read property 'execute' of undefined

这是 app.js (main) 中的代码

const Discord = require('discord.js')
const  Collection  = require('discord.js')
const client = new Discord.Client( intents: ["GUILDS", "GUILD_MESSAGES"] )
const fs = require("fs")

const PREFIX = ','

client.commands = new Collection()

const files = fs
    .readdirSync("./src/commands")
    .filter((file) => file.endsWith(".js"))

for(const file of files) 
    const command = require (`./src/commands/$file`)
    client.commands.set(command.name, command);


if(process.env.NODE_ENV !==  `production`) 
    require('dotenv').config()


client.on('ready', () => 
    console.log(`Logged in as $client.user.tag!`);
    client.user.setActivity(process.env.STATUS_NAME,  type: process.env.STATUS_TYPE )
    client.user.setStatus(`$process.env.PROFILE_TYPE`)
);

client.on('messageCreate', message => 
    if(message.author.bot) return;
    if(!message.content.startsWith(PREFIX)) return;
    let args = message.content.substring(PREFIX.length).split(" ");
    client.commands.get(args[0]).execute(message);
);

client.login(process.env.TOKEN)

ping.js 中的这个

module.exports = 
     name: 'ping',
     description: 'Ping commands adalah mengetes koneksi bot.',
     execute(message) 
         message.channel.send(`pong`);
     
 

【参考方案1】：

不是从参数获取命令的好方法，args[0] 在这里没有任何上下文，如果你只是输入 , 不会被注册为命令，而是你可以试试这个：

    const command = client.commands.get(args[0])
    if (!command) 
        return
     else 
        try 
            command.execute(message);
         catch (e) 
            console.log(e)
        
    

升力

    const commandName = args.shift().toLowerCase();
    
    if (!client.commands.has(commandName)) return;
    const command = client.commands.get(commandName)
     try 
        command.execute(message);
     catch (error) 
        console.log(error);
