我有这个代码:

import fs from 'fs'
import inquirer from 'inquirer'
import fetch from 'node-fetch'
import ytdl from 'ytdl-core'

process.env.YTDL_NO_UPDATE = true

    inquirer.prompt([
        {
            name: 'videoUrl',
            message: chalk.blue('Digite a url do vídeo:'),
            prefix: '>>'
        },
    ]).then(async (answers) => {
        const regUrl = /^https?:\/\/(?:www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b(?:[-a-zA-Z0-9()@:%_\+.~#?&\/=]*)$/

        const url = answers.videoUrl
        if (!regUrl.test(url)) throw new Error('Url inválida!')
        if (!url.includes('youtube')) throw new Error('Url não encontrada no YouTube')

        const name = await getNameByUrlMusic(url)
        console.log(name)

        const folder = await chooseDestinationFolderForTheFiles()
        console.log(folder)

        uploadMusic(url, name, folder)
    }).catch(error => {
        console.log(chalk.red('\n', error.message, '\n'))
        init()

}

}

init()

它一直工作到几天前,现在我开始得到这个错误,有人知道它可能是什么吗:

evalmachine.<anonymous>:25
[])||(0,c[2])((0,c[45])((0,c[25])(c[21],c[55],(0,c[11]) ()),c[2],(0,c[86])(c[55],c[53]),c[13],c[77],c[27]),c[52], c[62],c[74]),1==c[43]&&((0,c[45])((0,c[2])((0,c[13])(c[65 +Math.pow(3,2)%391],c[85]),c[78],c[35],c[68]),c[2],((0,c[76])( c[3],c[77]),c[40])(c[77]),c[40],c[87]),1)||(((((0,c[13]) (c[87],c[65]),c[52])(c[46],c[Math.pow(5,3)%149+-51]),c[47])(c[63 ],c[1]),c[62])(c[50],c[18]),c[28])(c[56],c[50])};lma(ncode);

我希望视频在最后下载,但我在try块中得到了这个错误消息,它缺少一个catch或finally,但最奇怪的是,我在代码中没有try块

实际上有一个bug,临时的解决方法是:
package.json中,将需要ytdl的行改为:
"ytdl-core": "https://github.com/khlevon/node-ytdl-core.git#v4.11.3-patch.1"
这个效果很好
