類型錯誤：無法讀取未定義的屬性（讀取“回復”）- discord.js v14

Question

我的朋友讓我給他做一個 discord 機器人，最近當我在https://discordjs.guide的幫助下開始制作機器人時，在制作 ping.js 時發生錯誤。 當我嘗試調用client.ws.ping時，出現錯誤： TypeError: Cannot read properties of undefined (reading 'ws')

在到處尋找可能的修復方法之后，我偶然發現了這篇文章TypeError: Cannot read properties of undefined (reading 'ws') - Discord.js V14描述了這個問題。

一旦我解決了這個問題，又發生了另一個錯誤，我不知道該怎么做： TypeError: Cannot read properties of undefined (reading 'reply')

平.js：

const { SlashCommandBuilder } = require('@discordjs/builders');

module.exports = {
    data: new SlashCommandBuilder()
        .setName('ping')
        .setDescription('Display the latency'),
    async execute(client, interaction) {
        await interaction.reply(`Latency is ${Date.now() - interaction.createdTimestamp}ms. API Latency is ${client.ws.ping}ms`);
    },  
};

完整錯誤：

任何幫助將不勝感激，在此先感謝。

Answer 1

要解決此問題，您需要確保已定義interaction object 並在嘗試使用它之前具有reply屬性。

這是一些代碼示例：

async execute(client, interaction) {
  if (!interaction || !interaction.reply) return;

  await interaction
  .reply(`Latency is ${Date.now() - interaction.createdTimestamp}ms. API Latency is ${client.ws.ping}ms`);
}

Answer 2

嘗試將 (main/index.js) 更改為：

const fs = require('node:fs');
const path = require('node:path');
const { Client, Collection, Events, GatewayIntentBits } = require('discord.js');
require('dotenv').config()

const client = new Client({ intents: [GatewayIntentBits.Guilds] });

client.commands = new Collection();
const commandsPath = path.join(__dirname, 'commands');
const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));

for (const file of commandFiles) {
    const filePath = path.join(commandsPath, file);
    const command = require(filePath);
    if ('data' in command && 'execute' in command) {
        client.commands.set(command.data.name, command);
    } else {
        console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
    }
}

client.on(Events.InteractionCreate, async interaction => {
    if (!interaction.isChatInputCommand()) return;

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

    if (!command) return;

    try {
        await command.execute(client, interaction);
    } catch (error) {
        console.error(error);
        await interaction.reply({ content: 'There was an error while executing this command!', ephemeral: true });
    }
});

const eventsPath = path.join(__dirname, 'events');
const eventFiles = fs.readdirSync(eventsPath).filter(file => file.endsWith('.js'));

for (const file of eventFiles) {
    const filePath = path.join(eventsPath, file);
    const event = require(filePath);
    if (event.once) {
        client.once(event.name, (...args) => event.execute(...args));
    } else {
        client.on(event.name, (...args) => event.execute(...args));
    }
}

client.login(process.env.TOKEN);

錯誤的部分在這里：

    try {
        await command.execute(interaction); // U must add client for it (command.execute(client,interaction))
    } catch (error) {
        console.error(error);
        await interaction.reply({ content: 'There was an error while executing this command!', ephemeral: true });
    }
