node.js - Nodejs YouTube : Spawn unknown error

Question

我在nodejs中的代码是这样的:-

var fs = require('fs');
var youtubedl = require('youtube-dl');
var video = youtubedl('http://www.youtube.com/watch?v=90AiXO1pAiA',
  // Optional arguments passed to youtube-dl.

  // Additional options can be given for calling `child_process.execFile()`.
  );

// Will be called when the download starts.

video.on('info', function(info) {
  console.log('Download started');
  console.log('filename: ' + info.filename);
  console.log('size: ' + info.size);
});

video.pipe(fs.createWriteStream('myvideo.mp4'));

我收到此错误:-

您还可以建议另一种制作 YouTube 下载器的方法。

Answer 1

我在 Windows 上遇到同样的问题，我将其修复为:

第 1 步:转到此link : https://rg3.github.io/youtube-dl/download.html

第 2 步:下载Windows exe (sig - SHA256 7071c7a2.....................)

第 3 步:将其替换为 \node_modules\youtube-dl\bin

第 4 步:运行您的代码:

const fs = require('fs');
const youTube = require('youtube-dl');
const video = youTube('http://www.youtube.com/watch?v=90AiXO1pAiA');

// called when the download starts.
video.on('info', function(info) {
    console.log('Download started');
    console.log('filename: ' + info.filename);
    console.log('size: ' + info.size);
});

video.pipe(fs.createWriteStream('downloads/downloaded_video.mp4'));

第 5 步:预期控制台输出:

/*  Sample Output   */
/*
    Download started
    filename: lol-90AiXO1pAiA.webm
    size: 1029843
    NOTE: File will be downloaded in downloads folder
*/

完整文件和正在运行的项目:
