Discord.js - 角色中的用户通过 DM 添加

Question

我想将用户添加到角色时遇到问题。

我的代码：

console.log(client.guild.roles.cache.get('720257839259451393'));

我从机器人那里得到：

    TypeError: Cannot read property 'roles' of undefined
        at Request._callback (/home/DiscordBot/main.js:127:62)
        at Request.self.callback (/home/DiscordBot/node_modules/request/request.js:185:22)
        at Request.emit (events.js:315:20)
        at Request.<anonymous> (/home/DiscordBot/node_modules/request/request.js:1154:10)
        at Request.emit (events.js:315:20)
        at IncomingMessage.<anonymous> (/home/DiscordBot/node_modules/request/request.js:1076:12)
        at Object.onceWrapper (events.js:421:28)
        at IncomingMessage.emit (events.js:327:22)
        at endReadableNT (_stream_readable.js:1224:12)
        at processTicksAndRejections (internal/process/task_queues.js:84:21)

Answer 1

该错误意味着公会未定义。 有人在机器人的 dms 中使用该命令。 您只需要一个简单的 if 语句

if(message.guild)
{
    //The command is used in server
}else
{
   //The command is used in dms
}
