我正在制作一個(gè)不和諧的機(jī)器人，我主要學(xué)習(xí)了 discord.js 的 v11，當(dāng)我在不和諧中創(chuàng)建一個(gè) unban 命令時(shí)，當(dāng)我完成時(shí)，我運(yùn)行了該命令，它給出了錯(cuò)誤“TypeError：無法讀取屬性” hasPermission' of undefined"，這是我的代碼。順便說一句，它是一個(gè)命令處理程序module.exports = {    name : 'unban',    execute(client, message, args){       if(!message.member.hasPermission(["BAN_MEMBERS"])) return message.channel.send("You dont have permission to perform this command!")    if(isNaN(args[0])) return message.channel.send("You need to provide an ID.")    let bannedMember =  client.users.fetch(args[0])        if(!bannedMember) return message.channel.send("Please provide a user id to unban someone!")    let reason = args.slice(1).join(" ")        if(!reason) reason = "No reason given!"    if(!message.guild.me.hasPermission(["BAN_MEMBERS"])) return message.channel.send("I dont have permission to perform this command!")|    message.delete()    try {        message.guild.members.unban(bannedMember, reason)        message.channel.send(`**${bannedMember.tag}** has been unbanned from the guild!`)    } catch(e) {        console.log(e.message)    }}No idea what the problem is.
