Javascript 使用用户ID的Discord.JS Avatar命令

我想使用用户id/提及的化身命令。我可以使用提及，但是我不能使用用户ID

这是我目前的代码：

const Discord=require'Discord.js'； module.exports={ 名称：'阿凡达'， 描述：'阿凡达'， 别名：['av']， 冷却时间：5， 异步执行消息，args{ 让member=message.indications.users.first | | message.guild.members.cache.getargs[0]| | message.author； 让avatar=member.displayAvatarURL{size:1024，dynamic:true}； const embed=new Discord.MessageEmbed .setAuthoravatar，message.username .setTitle`Avatar` .setImageavatar .setColorBLACK .setAuthormember.username、头像、头像； message.channel.sendebed； }, }; 无论何时运行此代码，我都会收到以下错误：

该方法仅对用户可用。这意味着它可以处理message.indications.users.first或message.author，因为它们返回用户，但不能处理message.guild.members.cache.getargs[0]，因为它返回GuildMember

如果存在args[0]且members.cache.get返回一个GuildMember，请获取其属性，以便以后也可以获取其头像

以下工作很好：

让user=message.notices.users.first ||message.guild.members.cache.getargs[0]？.user ||message.author； 让avatar=user.displayAvatarURL{size:1024，dynamic:true}
