Question

因此，我正在将我的机器人更新为discord.js V12，该命令出现错误。（节点：553）UnhandledPromiseRejectionWarning：TypeError：无法读取未定义的属性“ filter”

Node.js是Discord.js的当前版本，我知道它是否与代码有关

const { MessageEmbed } = require("discord.js");
const { stripIndents } = require("common-tags");
const { getMember, formatDate } = require("../../functions.js");

module.exports = {
  config:{
    name: "whois",
    aliases: ["who", "user", "info"],
   category: "info",
    description: "Returns user information",
    usage: "[username | id | mention]"
  },
    run: (client, message, args) => {
        const member = getMember(message, args.join(" "));

        // Member variables
        const joined = formatDate(member.joinedAt);
        const roles = member.roles
            .filter(r => r.id !== message.guild.id)
            .map(r => r).join(", ") || 'none';

如果我删除.filter和.map，则会出现另一个错误，显示.createdAT

  // User variables
        const created = formatDate(member.user.createdAt);

        const embed = new MessageEmbed()
            .setFooter(member.displayName, member.user.displayAvatarURL({ dynamic:true }))
            .setThumbnail(member.user.displayAvatarURL({ dynamic:true }))
            .setColor(member.displayHexColor === '#000000' ? '#ffffff' : member.displayHexColor)
            .setAuthor(`${member.displayName} | WHOIS`, member.user.displayAvatarURL)

            .addField('Member information:', stripIndents`** Display name:** ${member.displayName}
            ** Joined at:** ${joined}
            ** Roles:** ${roles}`, true)

            .addField('User information:', stripIndents`** ID:** ${member.user.id}
            ** Username**: ${member.user.username}
            ** Tag**: ${member.user.tag}
            ** Created at**: ${created}`, true)

            .setTimestamp()

        if (member.user.presence.game) 
            embed.addField('Currently playing', stripIndents`** Name:** ${member.user.presence.activity.name}`);

        message.channel.send(embed);
    }
}

现在，这就是整个whois代码，我不知道还有什么需要更新。

Answer 1

要访问v12中的GuildMember的{{1}}集合，您需要使用roles。

cache

Answer 2

Discord.js指南：

v12引入了管理器的概念，您将不再能够在诸如Client＃users之类的数据结构上直接使用诸如Collection＃get之类的收集方法。现在，在尝试使用收集方法之前，您将必须直接在管理器上请求缓存。直接在管理器上调用的任何方法都将调用API，例如GuildMemberManager＃fetch和MessageManager＃delete

OLD：client.users.get（'123456789012345678'）;

新功能：client.users.cache.get（'123456789012345678'）;

OLD：channel.messages.get（'123456789012345678'）;

新功能：channel.messages.cache.get（'123456789012345678'）;

OLD：guild.members.get（'123456789012345678'）;

新功能：guild.members.cache.get（'123456789012345678'）;
