类型错误：无法读取未定义的 Discord.js 的属性“set”

问题描述

我正在使用 discord.js，这是我的代码：

const client = new discord.Client();

const fs = require('fs');
const { get } = require('http');

client.commands = new discord.Collection();

const commandFiles = fs.readdirsync('./Commands/').filter(file => file.endsWith('.js'));

const set = new Set();

for(const file of commandFiles){
  const command = require(`./Commands/${file}`);

  client.command.set(command.name,command);
}

const config = require('./config.json');

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

client.on('message',msg => {
  if (!msg.content.startsWith(prefix) || msg.author.bot) return;

  const args = msg.content.slice(prefix.length).trim().split('/ +/ ');
  const command = args.shift().toLowerCase();
  // ...

  if (!client.commands.has(commandName)) return;

  const Command = client.commands.get(commandName);

  try {
     Command.execute(message,args);
  } catch (error) {
  // ...
  }

  try {
    client.commands.get(command).execute(message,args);
  } catch (error) {
    console.error(error);
    message.reply('there was an error trying to execute that command!');
  }

});
client.on('message',msg => {
  if (msg.content === 'ping') {
    client.commands.get('ping').execute(message,args);
  }else if (msg.content === 'pong') {
    msg.reply('Ping!')
  }else if (msg.content === `${prefix}beep`) {
    msg.channel.send('Boop!');
  }else if (msg.content === `${prefix}boop`) {
    msg.channel.send('Beep!');
  }else if (msg.content === `${prefix}server`) {
    msg.channel.send(`This server's name is: ${msg.guild.name}\nTotal members: 
    ${msg.guild.memberCount}`);
  }else if (msg.content === `${prefix}user-info`) {
    msg.channel.send(`Your username: ${msg.author.username}\nYour ID:    ${msg.author.id}`);
  }

});

const { prefix,token } = require('./config.json');
//...

client.login(config.token);

她是我的错误，在你问之前：是的，我有一个 config.json。

错误：

client.command.set(command.name,command);

这是我的问题，使我无法打开我的机器人并运行我正在测试的命令，所以我真的需要帮助。

解决方法

如您所见，client.command 没有 .set，但 client.commands 是

解决方案：

client.commands.set(command.name,command);
