已尝试升级youtube-dl（pip install --upgrade youtube-dl）及考虑提交bug，但认为问题出在自身环境，需要针对性解决办法。

可行解决办法 #

1. 切换到yt-dlp替代youtube-dl #

youtube-dl已长期停止维护，无法适配YouTube页面结构的更新。yt-dlp是其活跃分支，兼容性和更新频率更优：

• 安装yt-dlp：

  pip install yt-dlp
  

• 修改代码适配：

  import yt_dlp
  
  video_url = "https://www.youtube.com/watch?v=w9Fcgdlw-Nc"
  desired_format = 'mp4'
  
  ydl_opts = {
      'format': desired_format,
  }
  
  with yt_dlp.YoutubeDL(ydl_opts) as ydl:
      ydl.download([video_url])
  

2. 检查并配置网络代理 #

若处于无法直接访问YouTube的环境，需为工具配置代理：

• 在配置中添加代理信息（根据你的代理类型调整）：

  ydl_opts = {
      'format': desired_format,
      'proxy': 'http://your-proxy-address:port', # 或socks5://your-socks-proxy:port
  }
  

3. 验证视频访问权限 #

手动打开目标视频链接，确认：

• 视频未设置地区限制、年龄限制或需要登录才能观看
• 若需登录，可导出浏览器的Cookie文件，在配置中添加：

  ydl_opts = {
      'format': desired_format,
      'cookiefile': 'path/to/your/cookie/file.txt',
  }
