Javascript Discord.js v12 TypeError:无法读取属性'；获得许可'；未定义的

我做了一个添加角色命令，并为其添加了权限。但是，在运行命令时，我得到一个错误。这是我的密码：

const { MessageEmbed } = require('discord.js');
module.exports = {
    name: "addrole",
    aliases: ["ar"],
    description: "Adds a role to a user",
    async execute(client, message, args) {
        if (!message.member.hasPermission('MANAGE_ROLES')) return message.channel.send('NO PERMS')
        if (!message.guild.me.hasPermission('MANAGE_ROLES')) return message.channel.send('NO PERMS')
        const member = message.guild.members.cache.get(args[0]);
        if (!member)
            return message.channel.send('Please mention a user or provide a valid user ID');
        if (member.roles.highest.position >= message.member.roles.highest.position)
            return message.channel.send('You cannot add a role to someone with an equal or higher role');

        const role = message.guild.roles.cache.get(args[1]);

        let reason = args.slice(2).join(' ');
        if (!reason) reason = '`None`';
        if (reason.length > 1024) reason = reason.slice(0, 1021) + '...';

        if (!role)
            return message.channel.send('Please mention a role or provide a valid role ID');
        else if (member.roles.cache.has(role.id)) // If member already has role
            return message.channel.send('User already has the provided role');
        else {
            try {

                // Add role
                await member.roles.add(role);
                const embed = new MessageEmbed()
                    .setTitle('Add Role')
                    .setDescription(`${role} was successfully added to ${member}.`)
                    .addField('Moderator', message.member, true)
                    .addField('Member', member, true)
                    .addField('Role', role, true)
                    .addField('Reason', reason)
                    .setFooter(message.member.displayName, message.author.displayAvatarURL({ dynamic: true }))
                    .setTimestamp()
                    .setColor(message.guild.me.displayHexColor);
                message.channel.send(embed);
            } catch (err) {
                return message.channel.send('Please check the role hierarchy or if the role is managed by an integeration or system', err.message);
            }
        }
    }
}

正如我前面提到的，我得到一个错误：

我在每个命令中使用相同的权限代码，但是第一次出现这个错误。你能帮我吗？提前感谢

尝试制作

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

into:

const Discord=require（'Discord.js'）

（显然是编辑嵌入）在第一个

if

语句上方添加一个控制台日志，并检查const{MessageEmbed}=require（'Discord.js'）实际包含的消息into:

const Discord=require（'Discord.js'）
