Question

所以我做了一个静音和取消静音命令，静音的效果很好，我只需要添加一些东西，取消静音的也很好用，但是当没有提到的人（例如 q!unmute 而不是 q!unmute [ user]) 机器人崩溃了，我尝试了 catch 和那些东西，但我真的不明白它们是如何工作的，我对 js 很陌生，这是应该发送“你必须提及用户”错误的字符串：

if (!member) return message.channel.send("You have to mention a valid member");

这是剩下的代码：

module.exports = {
    name: 'unmute',
    description: 'unmutes a muted member',
    execute(message, args, Discord) {

        if (message.member.hasPermission('MANAGE_ROLES')) {

            const role = message.guild.roles.cache.find(role => role.name === 'Muted');
            const member = message.mentions.members.first();
            var unmuteChannel = message.guild.channels.cache.find(channel => channel.name.includes("modlogs"));

            const unmuteEmbed = new Discord.MessageEmbed()
            .addField("Unmuted user", member)
            .setFooter(`Unmuted by ${message.author.tag}`)
            .setTimestamp();

            
            member.roles.remove(role);
            message.channel.send(`${member} Has Been Unmuted`);
            unmuteChannel.send(unmuteEmbed); 
        
        if (!member) return message.channel.send("You have to mention a valid member");

        }
        
    }
}

希望能帮到你

在您的代码中，您正在检查提到的用户是否为空，但它位于函数的末尾。我认为在获得值之后放置 if 应该可以：

module.exports = {
    name: 'unmute',
    description: 'unmutes a muted member',
    execute(message, args, Discord) {

        if (message.member.hasPermission('MANAGE_ROLES')) {

            const role = message.guild.roles.cache.find(role => role.name === 'Muted');
            const member = message.mentions.members.first();
            if (!member) return message.channel.send("You have to mention a valid member");

            var unmuteChannel = message.guild.channels.cache.find(channel => channel.name.includes("modlogs"));

            const unmuteEmbed = new Discord.MessageEmbed()
            .addField("Unmuted user", member)
            .setFooter(`Unmuted by ${message.author.tag}`)
            .setTimestamp();

            
            member.roles.remove(role);
            message.channel.send(`${member} Has Been Unmuted`);
            unmuteChannel.send(unmuteEmbed); 
        }
        
    }
}

移动

if (!member) return message.channel.send("You have to mention a valid member");

在您定义成员的下方。

const member = message.mentions.members.first();

当我的取消静音命令中没有提及时，discord.js bot 崩溃
