Javascript 我的discord机器人不会在每次尝试时发送命令，它会脱机

我希望有人能帮忙，我和我的朋友们一直在努力修复错误，但我们无法修复它 我会将错误发送给任何能提供帮助的人， 我和我的朋友在命令中有命令，我已经发出了命令，但我知道他们给了我们错误。

只要在声明

命令后移动这一行（
如果（！Client.commands.has（command））return；
）。那它就可以正常工作了

const Discord = require('discord.js')
const Client = new Discord.Client();
const {prefix,token} = require('./config.json');
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('Ready!');
});

Client.on('message', message => {
  
    if (!message.content.startsWith(prefix) || message.author.bot) return;
  if (!Client.commands.has(command)) return;

  const args = message.content.slice(prefix.length).trim().split(/ +/);
  const command = args.content().toLowerCase();
  
  try {
    Client.commands.get(command).execute(message, args);
  } catch (error) {
    message.reply('error')
  }
});

错误承诺{}准备好了/home/runner/Discord/index.js:23如果（！Client.commands.has（command））返回；^ReferenceError:初始化之前无法访问“命令”
