DisTubeError [INVALID_TYPE]："音量"的预期'number'，但'50'不一致.js V13

Question

我正在尝试制作一个Discord音乐机器人。所有的代码工作正常，但在Volume命令中，当我执行!volume 50:

时，我得到这个错误

throw new __1.DisTubeError("INVALID_TYPE", "number", volume, "volume");
^
DisTubeError [INVALID_TYPE]: Expected 'number' for 'volume', but got '50'

这是我的代码:

const { guild, channel, member } = message;
if (
member.roles.cache.has('926674590200123502') ||
member.roles.cache.has('945435842258808862') ||
member.roles.cache.has('928717168001024020') ||
member.roles.cache.has('935939126123974726') ||
member.permissions.has(Permissions.FLAGS.ADMINISTRATOR)
) {
const voicechannel = member.voice.channel;
if (!voicechannel)
return message.reply(
'You must be in a voice channel to use Music commands',
);
if (guild.me.voice.channelID && voicechannel.id !== guild.me.voice.channelID)
return message.reply(
`I am already playing music in <#${guild.me.voice.channelID}>`,
);
const volume = args[0];
if (volume > 100 || volume < 1)
return message.reply('the volume must be a number between 1 and 100');
await client.distube.setVolume(voicechannel, volume);
await message.reply(`🔊 volume set to ${volume}`);
} else return message.reply("You can't use this command");

这是因为'50'不是数字而是字符串。尝试先解析它:

const volume = parseInt(args[0], 10);
if (isNaN(volume)) 
return message.reply('Volume must be a valid number');
if (volume > 100 || volume < 1 )
return message.reply('Volume must be a number between 1 and 100');
