Question

因此，无论何时我发送了错误的命令，例如 !pong（其中！ping 是正确的命令），机器人都会返回以下错误：

<块引用>

(if(command.permissions.length){ ^

TypeError: 无法读取未定义的属性“权限”

即使我删除了整个权限代码，它也会给我一个

TypeError: 无法读取未定义的属性 'users'

而且只有当我有错误的命令时 !pong 没有命令或 !me 任何带有不是实际命令的前缀的东西。下面是我使用的代码

Message.js

<块引用>

require('dotenv').config();

const cooldowns = new Map();

module.exports = (Discord, client, message) =>{ const 前缀 = process.env.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) || client.commands.find(a => a.aliases && a.aliases.includes(cmd));
const validPermissions = [

  ]

  if(command.permissions.length){
    let invalidPerms = []
    for(const perm of command.permissions){
      if(!validPermissions.includes(perm)){
        return console.log(`Invalid Permissions ${perm}`);
      }
      if(!message.member.hasPermission(perm)){
        invalidPerms.push(perm);
      }
    }
    if (invalidPerms.length){
      return message.channel.send(`Missing Permissions: \`${invalidPerms}\``);
    }
  }



if(!cooldowns.has(command.name)){
    cooldowns.set(command.name, new Discord.Collection());
}

const current_time = Date.now();
const time_stamps = cooldowns.get(command.name);
const cooldown_ammount = (command.cooldown) * 1000;

if(time_stamps.has(message.author.id)){
    const expiration_time = time_stamps.get(message.author.id) + cooldown_ammount;

    if(current_time < expiration_time){
        const time_left = (expiration_time - current_time) / 1000;

        return message.reply(`Please wait ${time_left.toFixed(1)} more seconds before using ${command.name}`)
    }
}

time_stamps.set(message.author.id, current_time);
setTimeout(() => time_stamps.delete(message.author.id), cooldown_ammount);

try{
    command.execute(message,args, cmd, client, Discord);
} catch (err){
    message.reply("There was an error trying to execute this command!");
    console.log(err);
}
 }

ping.js

module.exports = { 名称: 'ping', 冷却时间：10，权限：["SEND_MESSAGES",], 描述：“这是一个 ping 命令！”, 执行（客户端，消息，参数，cmd，不和谐）{ message.channel.send('pong!'); } }

在你的 message.js 中，声明 command 之后，你需要检查它是否为 undefined 或 null

const command = client.commands.get(cmd) || client.commands.find(a => a.aliases && a.aliases.includes(cmd));
if(!command) return;

编辑：您的错误来自此处：

command.execute(message,args, cmd, client, Discord);
//^^how you execute
execute(client, message, args, cmd, Discord){ message.channel.send('pong!'); }
//^^how you define it

正如你所看到的，你把它们放在了错误的顺序中。
