Question

Gang.findOne({leaderUserID: message.author.id, leaderUserName: message.member.user.tag, serverID: message.guild.id}, (err, gang) => {
        if(err) console.log(err);
        
        let embed = new Discord.MessageEmbed()
        .setTitle("Gang")
        .setColor("4000FF")
        .setThumbnail(message.author.displayAvatarURL)
        
        gangName = message.content.substring(message.content.indexOf(" ") + 1, message.content.length);

        if(!gang){
                const newGang = new Gang({
                leaderUserID: message.author.id,
                leaderUserName: message.member.user.tag,
                serverID: message.guild.id,
                gangName: gangName,
                points: "1"
            });

            guild.roles.create({
                data: {
                name: gangName,
                color: `GREY`
                },
                reason: `Gang created by ${message.member.user.tag} at ${message.timestamp}`
            });
            

            
            let role = message.guild.roles.cache.find(guild => guild.name === gangName);
            
            console.log(`role = ${role}`);
            member.roles.add(role);

            
            
            newGang.save().catch(err => console.log(err));
            
            
            embed.addField("Gang Creation", "-15 points", true);
            embed.addField("Gang Name", gangName, true);
            message.channel.send(embed);

            return;

除分配角色外，其他所有操作均有效。我将帮派名称设置为命令的第二部分，使用该名称创建角色，然后将角色设置为 let role = message.guild.roles.cache.find(guild => guild.name === gangName); 但随后，角色的console.log显示为“未定义”。

它如何未定义？我刚刚创建了角色，然后进行搜索。

guild.roles.create是一个异步函数，因此您可以使用await

let role = await guild.roles.create({
    data: {
        name: gangName,
        color: `GREY`
    },
    reason: `Gang created by ${message.member.user.tag} at ${message.timestamp}`
});

console.log(`role = ${role}`);
member.roles.add(role);

为什么按名称查找我的角色返回未定义？
