        message.channel.send(`@${person.user.tag} has now been muted for ${ms(ms(time))}`);

        setTimeout(function(){
            person.addrole(mainrole.id);
            person.removerole(muterole.id);
            message.channel.send(`@${person.user.tag} has been unmuted!`)

Answer 1

addrole() 和 removerole() 无效。

使用roles.add() 和roles.remove()
