Discord抽奖报options.winnerCount非正整数错误求助

执行命令!gstart 30s 1 nitro时抛出options.winnerCount is not a positive integer. (val=1)报错，核心原因是类型不匹配：

• 你从命令参数args[2]中拿到的中奖人数是字符串类型的"1"，不是数字类型的1
• giveawaysManager对winnerCount字段做了严格校验，要求必须传入Number类型的正整数，字符串格式的数字即使值符合要求，也无法通过类型校验
• 你原有代码只做了值的合法性判断，没有将参数从字符串转为数字类型，传入start方法时仍然是字符串，因此触发报错。

只需要在读取中奖人数参数时直接将其转为整数类型，后续校验和传参都使用转换后的数字值即可，修改对应代码段如下：

1. 修改中奖人数变量的初始化和校验逻辑：

// Number of winners
let giveawayNumberWinners = parseInt(args[2]);
// If the specified number of winners is not a number
if(isNaN(giveawayNumberWinners) || giveawayNumberWinners <= 0){
    return message.channel.send(':x: You have to specify a valid number of winners!');
}

2. 启动抽奖的配置部分不需要额外改动，winnerCount直接传入转换后的变量即可，此时传入的是合法的数字类型正整数，不会再触发校验报错，其余原有配置保持不变：

bot.giveawaysManager.start(giveawayChannel, {
    // The giveaway duration
    time: ms(giveawayDuration),
    // The giveaway prize
    prize: giveawayPrize,
    // The giveaway winner count
    winnerCount: giveawayNumberWinners,
    // Who hosts this giveaway
    hostedBy: message.author,
    // Messages
    messages: {
        giveaway: "🎉🎉 <strong>GIVEAWAY</strong> 🎉🎉",
        giveawayEnded: "🎉🎉 <strong>GIVEAWAY ENDED</strong> 🎉🎉",
        timeRemaining: "Time remaining: <strong>{duration}</strong>!",
        inviteToParticipate: "React with 🎉 to participate!",
        winMessage: "Congratulations, {winners}! You won <strong>{prize}</strong>!",
        embedFooter: "Giveaways",
        noWinner: "Giveaway cancelled, no valid participations.",
        hostedBy: "Hosted by: {user}",
        winners: "winner(s)",
        endedAt: "Ended at",
        units: {
            seconds: "seconds",
            minutes: "minutes",
            hours: "hours",
            days: "days",
            pluralS: true
        }
    }
});

message.channel.send(`Giveaway started in ${giveawayChannel}!`);
