【问题描述】：

我正在尝试制作一个不和谐机器人，当您键入 !mute @user 时，它会为他们提供静音角色，如果没有静音角色，它会创建一个并将其添加给用户。这是我的代码：否则 if (message.content.startsWith(${prefix}mute)) {

let role = message.guild.roles.cache.find(x => x.name == 'mute');
if(!role) {
    guild.roles.create({
        data: {
          name: 'mute haha',
          color: 'GRAY',
        },
        reason: 'you probably spammed',
      })
        .then(console.log)
        .catch(console.error);
    }
const user = message.mentions.users.first();
if (user) {
    const member = message.guild.members.resolve(user);
    if (member) {
        let mute = message.guild.roles.cache.find(role => role.name === "mute");
        member.addRole(mute);
    } else {
        message.channel.send("That user isn't in this server");
    }
} else {
    message.channel.send("You didn't mention the user to kick");
}

这是我尝试运行它时遇到的错误：

C:\Users\COOKIE\Desktop\bot\main.js:157
                        guild.roles.create({
                              ^

【问题讨论】：

您在整个文件中一直使用message.guild，为什么您只在该行中使用guild

标签： javascript node.js discord.js

【解决方案1】：

错误指出guild没有定义，那是因为guild实际上是消息对象的一个属性，所以你应该这样做

message.guild.roles.create()

并确保您检查该命令是在公会中运行而不是在用户的 DM 中运行，否则公会将是未定义的

if (!message.guild) return console.log('command is being run outside a server');
message.guild.roles.create(/* do ur stuff*/);
// rest of the code
