Discord.js -如何记录角色更改？

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

client.on('guildMemberUpdate', (oldMember, newMember) => {
  // 在这里处理角色更改的逻辑
});

client.on('guildMemberUpdate', (oldMember, newMember) => {
  const oldRoles = oldMember.roles.cache;
  const newRoles = newMember.roles.cache;

  // 比较角色是否发生了变化
  if (oldRoles.size !== newRoles.size || !oldRoles.every(role => newRoles.has(role.id))) {
    // 角色发生了变化
    console.log('角色发生了变化');
  }
});
