我的 Discord 機器人的提及幫助命令不起作用。 有人可以幫忙嗎？ （Discord.js，JavaScript）

Question

當提到我的機器人時，我希望它執行特定的命令。 但是，當它被提及時，它會引發一個錯誤，我將在我的代碼之后粘貼該錯誤。

PS：我使用命令處理程序。 PS 2：這個機器人托管在 repl.it

我的 index.js 代碼：

const fs = require('fs');
const Discord = require('discord.js');
const hosting = require('./hosting.js');
const client = new Discord.Client();
const token = process.env.botToken;
const {prefix} = require('./config.json');

module.exports = client

client.commands = new Discord.Collection();
const commandFolders = fs.readdirSync('./commands');

for (const folder of commandFolders) {
    const commandFiles = fs.readdirSync(`./commands/${folder}`).filter(file => file.endsWith('.js'));
    for (const file of commandFiles) {
        const command = require(`./commands/${folder}/${file}`);
        client.commands.set(command.name, command);
    }
}




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', () => {
  client.user.setPresence({activity: {name: '!1help', type: 'LISTENING'}, status: 'idle'});
  console.log("Bot is running.");
  console.log(client.user.username);
});

const escapeRegex = str => str.replace(/[.*+?^${}()|[\]\\]/g, '\\$&');

client.on('message', message => {

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();




if (message.content === "<@833376214609690674>" || message.content === "<@!833376214609690674>") {
  const mCommand = client.commands.get('help')
  mCommand.execute()
}

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

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

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

client.login(token);

我的 help.js 代碼（這是我希望我的機器人在提到它時執行的命令）：

const { prefix } = require('../../config.json');
module.exports = {
    name: 'help',
  category: "utility",
    description: 'Lists all available commands or info about a specific command.',
    usage: '[command name]',
    execute(message, args) {

const data = [];
const { commands } = message.client

if (!args.length) {
  data.push("Here's a list of all my commands:");
data.push(commands.map(command => command.name).join(', '));
data.push("\nYou can use `{prefix}help [command name]` to get info on a specific command!");

return message.author.send(data, { split: true })
    .then(() => {
        if (message.channel.type === 'dm') return;
        message.reply("I've sent you a DM with all my commands!");
    })
    .catch(error => {
        console.error(`Could not send help DM to ${message.author.tag}.\n`, error);
        message.reply("It seems like I can't DM you! Do you have DMs disabled? If so, please enable them.");
    });
}
const name = args[0].toLowerCase();
const command = commands.get(name) || commands.find(c => c.aliases && c.aliases.includes(name));

if (!command) {
    return message.reply("That's not a valid command!");
}

data.push(`**Name:** ${command.name}`);

if (command.aliases) data.push(`**Aliases:** ${command.aliases.join(', ')}`);
if (command.category) data.push(`**category:** ${command.category}`)
if (command.description) data.push(`**Description:** ${command.description}`);
if (command.usage) data.push(`**Usage:** ${prefix}${command.name} ${command.usage}`);

if (command.cooldown === undefined) {
  data.push(`**Cooldown:** 0 seconds`)
}
else if (command.cooldown === 1) {
  data.push(`**Cooldown:** ${command.cooldown} second`)
}
else {
  data.push(`**Cooldown:** ${command.cooldown} seconds`)
}

message.channel.send(data, { split: true });
},
};

help.js 文件的路徑：

./commands/utility/help.js

當 Discord 上提到機器人時，我在控制台中收到錯誤：

node v12.16.1

const { commands } = message.client
                             ^

Answer 1

execute(message, args) {

我需要在 index.js 中的 if function 中以這種方式傳遞執行和參數：

if (message.content === "<@833376214609690674>" || message.content === "<@!833376214609690674>") {
  const mCommand = client.commands.get('help')
  mCommand.execute(**message, args**)
}

Answer 2

比較您的命令處理程序和您自己的代碼以在提及時激活

你提到 function

mCommand.execute()

原始命令處理程序

command.execute(message, args);

如您所見，這兩者之間的區別是您的傳遞message, args但mCommand.execute()中沒有

由於您沒有傳遞任何參數，因此您無法從 help.js 中的help.js獲得任何信息

但是您嘗試訪問它們execute(message, args) {

並且由於沒有傳遞任何message ，因此未定義（args 也未定義）

簡單的修復將在下面

mCommand.execute() => mCommand.execute(message, args)

ps：你應該學習javascript，它會幫助你的未來
