从另一个文件节点js获取变量

Question

我正在尝试使用 Discord.js 制作一个 Discord 机器人，并且在文档中的指南中说要为每个命令创建一个单独的文件。

我目前遇到的问题是，当我运行命令部署时，文件中的所有数据都不可用。我已经尝试从指南中复制所有内容。

这是我的代码和输出：

ping.js

const { SlashCommandBuilder } = require('discord.js');

const data = new SlashCommandBuilder()
    .setName('ping')
    .setDescription('Replies with pong!')

部署命令.js

const { REST, Routes } = require('discord.js');
require('dotenv').config();
const fs = require('node:fs');
const { ClientID, GuildID } = require("./config.json");

const commands = [];
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

console.log("Hello World!")

// This is where the error happens
for (const file of commandFiles) {
    console.log(file)
    const command = require(`./commands/${file}`);
    console.log(command); // I dont know why this is empty
    console.log(command.data); // command.data should not be undefined
    commands.push(command.data.toJSON());
}

const rest = new REST({ version: '10' }).setToken(process.env.TOKEN);

(async () => {
    try {
        console.log(`Started refreshing ${commands.length} application (/) commands.`);

        const data = await rest.put(
            Routes.applicationGuildCommands(ClientID, GuildID),
            { body: commands },
        );

        console.log(`Successfully reloaded ${data.length} application (/) commands.`);
    } catch (error) {
        console.error(error);
    }
})();

输出

Hello World!
echo.js
{}
undefined
C:\Users\danho\Coding\node\DiscordBot\deploy-commands.js:16
        commands.push(command.data.toJSON());
                                   ^

TypeError: Cannot read properties of undefined (reading 'toJSON')
    at Object.<anonymous> (C:\Users\danho\Coding\node\DiscordBot\deploy-commands.js:16:29)

正如我所说，这几乎是从他们的官方示例here 中获取的代码的精确副本

我不知道是什么导致了这个问题，所以任何提示/帮助将不胜感激！

在ping.js 中，使用：

const { SlashCommandBuilder } = require('discord.js');

module.exports = {
  data: new SlashCommandBuilder()
    .setName('ping')
    .setDescription('Replies with pong!');
};
