Discord Bot运行userinfo命令报错moment is not defined如何解决

你已经完成了moment依赖的安装，但当前userinfo.js文件中并没有引入moment模块，导致代码调用moment()方法时无法识别对应对象，抛出未定义错误。

在userinfo.js文件的首行区域，添加moment模块的引入语句即可：

const moment = require('moment');

const { MessageEmbed } = require('discord.js');
const moment = require('moment');

module.exports = {
name: "userinfo",
aliases: ['ui'],
description: "Shows account stats",
execute(message, args, commandName, client, Discord) {
    const Target = message.mentions.users.first() || message.author;
    const Member = message.guild.members.cache.get(Target.id);

    const Response = new MessageEmbed()
    .setAuthor(`${Target.username}`, Target.displayAvatarURL({dynamic: true}))
    .setThumbnail(Target.displayAvatarURL({dynamic: true}))
    .setColor('NOT_QUITE_BLACK')
    .addField("User ID", `${Target.id}`, false)
    .addField("Roles", `${Member.roles.cache.map(r => r).join(' ').replace("@everyone", " ")}`)
    .addField("Server member since", `${moment(Member.joinedAt).format('MMMM Do YYYY, h:mm:ss a')}\n**-** ${moment(Member.joinedAt).startOf('day').fromNow()}`)
    .addField("Discord member since", `${moment(Member.createdAt).format('MMMM Do YYYY, h:mm:ss a')}\n**-** ${moment(Member.createdAt).startOf('day').fromNow()}`)
    message.reply({embeds: [Response]});
}
}
