客户端未在 discord bot 模块中定义

Question

我对任何类型的编程都不熟悉。在我的 discord bot 中，主文件查找执行命令的模块。

const Discord = require('discord.js');

require('dotenv').config();
const bot = new Discord.Client();

bot.commands = new Discord.Collection();
const botCommands = require('./commands');

Object.keys(botCommands).map(key => {
  bot.commands.set(botCommands[key].name, botCommands[key]);
});

const TOKEN = process.env.TOKEN;

bot.login(TOKEN);

bot.on('ready', () => {
  console.info(`Logged in as ${bot.user.tag}!`);
});

bot.on('message', msg => {
  const args = msg.content.split(/ +/);
  const command = args.shift().toLowerCase();
  console.info(`Called command: ${command}`);

  if (!bot.commands.has(command)) return;

  try {
    bot.commands.get(command).execute(msg, args);
  } catch (error) {
    console.error(error);
    msg.reply('Check it out! You *failed*.');
  }
});

其中一个命令应该在触发后向某个频道发送消息：

module.exports ={
    name: '!start',
    description: 'Starts the killing game',
    execute(msg, args) {
        client.on('ready', client => {
        client.channels.cache.get('724557257484009516').send('The killing game is about to start!');
        });
    },
};

但它出现了这个错误：

ReferenceError: client is not defined
    at Object.execute (D:\drpa-bot\big bin\commands\game-start.js:5:3)
    at Client.<anonymous> (D:\drpa-bot\big bin\index.js:28:31)

我该如何解决？

您没有将客户端变量从 index.js 文件传递​​到命令文件，也不要在命令中放置事件侦听器，这是非常糟糕的主意，而是执行以下操作：

execute(msg, args) {
    Let guild = msg.client.guilds.cache.get(‘ID of the guild in which the channel is in);
    guild.channels.cache.get('724557257484009516').send('The killing game is about to start!');
},

我使用了msg.client，因为来自discord.js documentation ：message.client 实例化此消息的客户端，所以你的机器人。
