我有一个问题，我真的不知道如何解决。当我尝试在我的代码中实现更改前缀命令时，我想使用它时遇到错误。首先，代码都在一个文件中并且工作正常，但是我拆分了文件，以便命令每个都有不同的文件。这是代码不再起作用的地方。我确定这是因为我不擅长 javascript，但请帮助我！

这是主文件：

const Discord = require("discord.js");
const config = require("./config.json");
const client = new Discord.Client();
const newUsers = [];
const fs = require("fs")

// Error en warning berichten.
client.on("error", (e) => console.error(e));
client.on("warn", (e) => console.warn(e));


// This loop reads the /events/ folder and attaches each event file to the appropriate event.
fs.readdir("./events/", (err, files) => 
  if (err) return console.error(err);
  files.forEach(file => 
    let eventFunction = require(`./events/$file`);
    let eventName = file.split(".")[0];
    // super-secret recipe to call events with all their proper arguments *after* the `client` var.
    client.on(eventName, (...args) => eventFunction.run(client, ...args));
  );
);

client.on("message", message => 
  if (message.author.bot) return;
  if(message.content.indexOf(config.prefix) !== 0) return;

  // This is the best way to define args. Trust me.
  const args = message.content.split(/\s+/g);
  const command = args.shift().slice(config.prefix.length).toLowerCase();

  // The list of if/else is replaced with those simple 2 lines:
  try 
    let commandFile = require(`./commands/$command.js`);
    commandFile.run(client, message, args);
   catch (err) 
    console.error(err);
  
);

exports.run = (client, message, args) => 
  if(!args || args.size < 1) return message.reply("Must provide a command name to reload.");
  // the path is relative to the *current folder*, so just ./filename.js
  delete require.cache[require.resolve(`./$args[0].js`)];
  message.reply(`The command $args[0] has been reloaded`);
;

client.login(config.token);

这是前缀文件：

exports.run = (client, message, args) => 
  const modRole = message.guild.roles.find("name", "Discord Admin");
  if (!modRole) 
    return console.log("The Discord Admin role does not exist.");

  if (!message.member.roles.has(modRole.id))
    return message.reply("You can't use this command.");

   // Verandert de prefix van de command (vb. "!prefix +" ontvangt de "+" dus word het "+prefix").
      let newPrefix = message.content.split(" ").slice(1, 2)[0];
      // Verandert de configuratie in memory
      config.prefix = newPrefix;
      // Slaat het bestand op.
      fs.writeFile("./config.json", JSON.stringify(config), (err) => console.error);

并且在配置文件中是："prefix":"!"

我确实尝试了很多东西，但我在 node.js 中保留了这个错误：
