如何在Discord.js中找到某个角色的人数？

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}`);
});

client.on('message', message => {
  if (message.content === '!roleCount') {
    const guilds = client.guilds.cache;

    guilds.forEach(guild => {
      const roles = guild.roles.cache;
      const targetRole = roles.find(role => role.name === '目标角色名称');

      if (targetRole) {
        const memberCount = targetRole.members.size;
        message.channel.send(`目标角色的人数为：${memberCount}`);
      }
    });
  }
});

client.login('YOUR_DISCORD_BOT_TOKEN');
