Discord.js仅使用ID管理角色

Question

我正在尝试编写一个discord.js机器人。 现在，我正在一个临时系统上工作，但是似乎找不到从具有用户ID的用户中删除角色的方法！ 我已经搜索了互联网的周围，但是似乎找不到任何对我有帮助的东西。
例如 Discord.js文档和白痴指南

我的代码：

exports.run = (client, message, args, config) => { if(!message.member.roles.some(r=>[config.BotMaster].includes(r.name))) return message.reply("Du behöver en högre rank!");
const mysql = require('mysql');
const con = mysql.createConnection({
    host: config.host,
    user: config.user,
    password: config.password,
    database: config.database
});

    let role = message.guild.roles.find("name", config.Muted);
    let member = message.mentions.members.first();
    let sql = "SELECT * FROM TempMute WHERE Time<=" + Date.now() + ' AND Unmuted!="True"'
    con.query(sql, function (err, rows) {
        if (err) return console.log(err);
        for (var i = 0; i < rows.length; i++) {
            var row = rows[i];
            var sql2 = "UPDATE TempMute SET Unmuted = 'True' WHERE Id = " + row.Id + ";";
            con.query(sql2, function (err, result) {
                if (err) return console.log(err);
                var Id = row.Name
                var unmute = client.fetchUser(Id)
                unmute.removeRole(role).catch(console.error);
            });
        };
    });
};

错误：

/home/pi/Documents/PinkBot/node_modules/mysql/lib/protocol/Parser.js:80
    throw err; // Rethrow non-MySQL errors
    ^

Answer 1

client.fetchUser(id)返回一个承诺，然后您将从中获得一个用户。 您无法从用户中删除角色。 您需要GuildMember才能删除角色。
而不是： var unmute = client.fetchUser(Id) ，您将需要以下内容：

message.guild.fetchMember(Id).then(guildMember => {
    guildMember.removeRole(role).catch(console.error);
})
