Discord.js - TypeError：無法讀取未定義的屬性（讀取“設置”）

Question

這是在 main.js 中：

const { Client, Intents, DiscordAPIError } = require('discord.js');

const Discord = require('discord.js');

const client = new Discord.Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });

const prefix = 'js!';

const fs = require('fs');

client.command = new Discord.Collection();

fs.readdir("./commands/", (err, files) => {
    if(err) console.error(error)
    let jsfiles = files.filter(f => f.split(".").pop() === "js")
    if (jsfiles.length <= 0) {
      return console.log("No commands to log in FOLDER NAME")
    }
    console.log(`Loading ${jsfiles.length} commands from FOLDER NAME...`)
    jsfiles.forEach((f,i) => {
      let props = require(`./commands/${f}`)
      console.log(`${i + 1}: ${f} loaded!`)
      client.commands.set(f, props)
    })
  });

client.once('ready',() => {
    console.log('bot is on')
});

client.on('message', message =>{
    if(!message.content.startsWith(prefix) || message.author.bot) return;
    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();

    if(command === 'ping'){
        let cmd = client.commands.get(command+".js")
            if (cmd) cmd.run(bot, message, args, prefix)
    } 
});

client.login('Prefix')

這是在 ping.js 中：

const { Client, Intents, DiscordAPIError } = require('discord.js');

const Discord = require('discord.js')

const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });

module.exports.run = async (client, message, args, prefix) => {
    var ping = Date.now() - message.createdTimestamp + " ms";

    message.channel.send('Ma ping is' + ` ${Date.now() - message.createdTimestamp}` + 'ms')
};
module.exports.help = {
  name: "ping",
  usage: "Ping Command",
};

但是如果我使用命令node .運行 main.js node . 在終端中，我收到此錯誤：

Loading 1 commands from FOLDER NAME...
1: ping.js loaded!
/home/ender/Desktop/Projects & Stuff/Coding/Discord Bot (JS)/main.js:23
      client.commands.set(f, props)
                      ^

TypeError: Cannot read properties of undefined (reading 'set')
    at /home/ender/Desktop/Projects & Stuff/Coding/Discord Bot (JS)/main.js:23:23
    at Array.forEach (<anonymous>)
    at /home/ender/Desktop/Projects & Stuff/Coding/Discord Bot (JS)/main.js:20:13
    at FSReqCallback.oncomplete (node:fs:188:23)

我使用 linux 作為我的主要操作系統，我使用的 node.js 版本是 v16.11.1，npm 版本是 8.0.0！

請幫忙，我最近開始使用discord.js，因為我意識到discord.py已經死了，我需要幫助！

正如@MrMythical 指出的那樣，唯一的問題是我忘記了client.command = new Discord.Collection();行中的“s” client.command = new Discord.Collection(); . 在我最后加上一個“s”后，它工作正常——沒有其他錯誤，所以這是我自己問題的答案！
