所以我正在制作一个可以播放音乐的机器人，我想要一个音乐测验命令（音乐开始播放，你需要找到名字和/或作者）。我编写了代码，但它卡在 What is the number of songs you want the quiz to have? 处。我找不到问题（我也没有发现错误）。
代码如下：
const { MessageEmbed } = require('discord.js');
const ytdl = require('ytdl-core');
const { PREFIX } = require('../../config')
const musictriviajson = require('../../JSON/musictrivia.json')
const db = require('quick.db');
module.exports = {
config: {
name: 'musictrivia',
category: 'music',
aliases: ['musicquiz', 'mt'],
description: "Music Trivia for You",
usage: "[amount of songs]",
accessableby: "everyone"
},
run: async (bot, message, args, ops) => {
let prefix;
let fetched = await db.fetch(`prefix_${message.guild.id}`);
if (fetched === null) {
prefix = PREFIX
} else {
prefix = fetched
}

};
ops.queue2.set(message.guild.id, triviaData)
var { channel } = message.member.voice;
const channeljoin = new MessageEmbed()

if (!channel)
return message.channel.send(channeljoin);

return message.channel.send('**A quiz or a song is already running!**');
triviaData.isTriviaRunning = true;
if (!args[0]) return message.channel.send("**What is the number of songs you want the quiz to have?**")
if (args[0] >= 5 && args[0] <= 15) {
var videoDataArray = musictriviajson.songs;
const randomXVideoLinks = getRandom(videoDataArray, args[0]);
const infoEmbed = new MessageEmbed()
.setColor('GREEN')
.setTitle('Starting Music Quiz')
.setDescription(
`Get ready! There are ${args[0]} songs, you have 30 seconds to guess either the singer/band or the name of the song. Good luck!
You can end the trivia at any point by using the end-trivia command`
);
