【中文标题】const commandFolders = readdirSync(\'./commands\'); ReferenceError：在 Object.<anonymous> 初始化之前无法访问“readdirSync”错误

【英文标题】：const commandFolders = readdirSync('./commands'); ReferenceError: Cannot access 'readdirSync' before initialization at Object.<anonymous> errorconst commandFolders = readdirSync('./commands'); ReferenceError：在 Object.<anonymous> 初始化之前无法访问“readdirSync”错误

【问题描述】：

我今天遇到了这个错误，试图从一个 youtube 视频中更改我的命令处理程序的一点点。视频来自 4 月，它似乎对这个人有用，但对我来说却没有。我尝试了很多东西，但我没有得到任何线索。我对此不太好，但我想像许多其他人一样开始，这个社区非常好，对我帮助很大，非常感谢你对我的支持！！我希望我能过去这个问题。

const Timeout = new Discord.Collection();


const bot = new Discord.Client(); 


const prefix = '$';

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


const ms = require('ms');

const readdirSync , read = require('fs');

for(const folder of commandsFolders)
    const commandFiles  = readdirSync(`./commands/$folder`).filter(file => file.endsWith('.js'));
    for(const file of commandFiles)
        const command = require(`./commands/$folder/$files`);
        bot.commands.set(command.name, command);
    


bot.on("error" , console.error);


bot.once('ready' , () => 
    console.log('M-am trezit din morti!');
);

bot.on("message" , async (message) =>
     if(message.author.bot) return;
     if(message.channel.type === 'dm') return;

     if(message.content.startsWith(prefix))
         const args = message.content.slice(prefix.length).trim().split(/ +/);

         const commandName = args.shift().toLowerCase();

         const command = bot.command.get(commandName) || bot.commands.find(cmd => cmd.aliases && cmd.aliases.includes(commandName));
         if(!command) return;

         if (command) 
             if(command.cooldown)
                 if(Timeout.has(`$command.name$message.author.id`)) return  message.channel.send(`Te rog asteapta! \`$ms(Timeout.get (`$command.name$message.author.id`) - Date.now(), long: true)\`Pana folosesti comanda din nou!`);
                 command.run(bot, message, args)
                 Timeout.set(`$command.name$message.author.id` , Date.now() + command.cooldown)
                 setTimeout(() =>
                     Timeout.delete(`$coomand.name$message.author.id`)
                 , command.cooldown)
              else command.run(bot, message, args); 
         
     
)

【参考方案1】：

所以你做错了，你想在你的代码中包含 fs 库之前使用 readdirSync。只需将 require 语句移到 readdirSync 上，它就可以工作了：

const bot = new Discord.Client(); 


const prefix = '$';

const readdirSync , read = require('fs');

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


const ms = require('ms');


for(const folder of commandsFolders)
    const commandFiles  = readdirSync(`./commands/$folder`).filter(file => file.endsWith('.js'));
    for(const file of commandFiles)
        const command = require(`./commands/$folder/$files`);
        bot.commands.set(command.name, command);
    


bot.on("error" , console.error);


bot.once('ready' , () => 
    console.log('M-am trezit din morti!');
);

bot.on("message" , async (message) =>
    if(message.author.bot) return;
    if(message.channel.type === 'dm') return;

    if(message.content.startsWith(prefix))
        const args = message.content.slice(prefix.length).trim().split(/ +/);

        const commandName = args.shift().toLowerCase();

        const command = bot.command.get(commandName) || bot.commands.find(cmd => cmd.aliases && cmd.aliases.includes(commandName));
         if(!command) return;

         if (command) 
             if(command.cooldown)
                 if(Timeout.has(`$command.name$message.author.id`)) return  message.channel.send(`Te rog asteapta! \`$ms(Timeout.get (`$command.name$message.author.id`) - Date.now(), long: true)\`Pana folosesti comanda din nou!`);
                 command.run(bot, message, args)
                 Timeout.set(`$command.name$message.author.id` , Date.now() + command.cooldown)
                 setTimeout(() =>
                     Timeout.delete(`$coomand.name$message.author.id`)
                 , command.cooldown)
              else command.run(bot, message, args);
