If you want to change a users nickname, you must make sure that the bot has permission to do so first. You can use the GuildMember#setNickname function like this:

 var pingeduser = message.guild.member(message.mentions.users.first()) ||
        message.guild.members.cache.get(args[0]);
      if (!pingeduser) return message.channel.send("Can't find user!");    
    var nick = message.content.split(" ").slice(1).join(" ");
    pingeduser.setNickname(nick);
