Discord.js pat命令

Question

我试图为我的不和谐机器人发出和拍拍命令，但它不起作用。

我收到以下错误：

码

const Discord = require('discord.js');
const { patch } = require('node-superfetch');
const superagent = require('superagent');
const customisation = require('../customisation.json');

module.exports = {
  name: "pat",
  description: "Pat someone UwU",
  aliases:["pat"],
  category: "fun",

  execute: async (client, message, args, tools) => {
    if (message.mentions.users.first().id)
    return message.reply("you almost mention someone to pat them");
    
    if (message.mentions.users.first().id) 
    return message.channel.send('UwU');

    const { body } = await superagent
    .get("https://nekos.life/api/pat");
    
    const embed = new Discord.MessageEmbed()
    .catch(body)
    .setColor("#3bb9ff")
    .setTitle(`i see that is, ${message.author.username} patted ${message.mentions.users.first().username}`) 
    .setImage(body.url)
    .setFooter(`© ${customisation.ownername}`);
    message.channel.send({embed})
}}

命令Index.js responsabile

const commandFiles = readdirSync(join(__dirname, "commands")).filter((file) => file.endsWith(".js"));
for (const file of commandFiles) {
  const command = require(join(__dirname, "commands", `${file}`));
  client.commands.set(command.name, command);
}

client.on("message", async (message) => {
  if (message.author.bot) return;
  if (!message.guild) return;

  const prefixRegex = new RegExp(`^(<@!?${client.user.id}>|${escapeRegex(PREFIX)})\\s*`);
  if (!prefixRegex.test(message.content)) return;

  const [, matchedPrefix] = message.content.match(prefixRegex);

  const args = message.content.slice(matchedPrefix.length).trim().split(/ +/);
  const commandName = args.shift().toLowerCase();

  const command =
    client.commands.get(commandName) ||
    client.commands.find((cmd) => cmd.aliases && cmd.aliases.includes(commandName));

  if (!command) return;

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

  const now = Date.now();
  const timestamps = cooldowns.get(command.name);
  const cooldownAmount = (command.cooldown || 1) * 1000;

  if (timestamps.has(message.author.id)) {
    const expirationTime = timestamps.get(message.author.id) + cooldownAmount;

    if (now < expirationTime) {
      const timeLeft = (expirationTime - now) / 1000;
      return message.reply(
        `please wait ${timeLeft.toFixed(1)} more second(s) before reusing the \`${command.name}\` command.`
      );
    }
  }

  timestamps.set(message.author.id, now);
  setTimeout(() => timestamps.delete(message.author.id), cooldownAmount);

  try {
    command.execute(message, args);
  } catch (error) {
    console.error(error);
    message.reply("There was an error executing that command.").catch(console.error);
  }
});

I您看到错误/当我可以升级代码时，请告诉我。，我的不和是IncarnateWill#6969。，如果您需要其他东西，请添加我，我将屏幕上共享bot.的代码。

好吧，message总是有一个mentions属性，即使没有提到(当消息中没有人提到时，message.mentions.users.first()返回undefined )。由于上面的代码看起来是正确的，如果您没有将message.mentions对象向下传递给execute方法，或者传递参数的顺序不对，那么唯一可能的方法是undefined。

更新：

在您的index.js中，您要像这样调用execute：command.execute(message, args)。您需要用正确的参数更新它：

// ...
try {
  command.execute(client, message, args)
} catch (error) {

// ...

在pat.js中

// ...
execute: async (client, message, args) => {
  // ...
}}

如果您有其他当前使用该顺序的命令，则可以添加client作为第三个参数，因此不需要更新它们，只需要更新这两个命令：

// in index.js

try {
  command.execute(message, args, client)
} catch (error) {

// in pat.js

execute: async (message, args, client) => {
  // ...
}}
