使用youtube_dl下载YouTube视频报错：Unable to extract uploader_id

我编写了如下Python代码用于下载YouTube视频：

import youtube_dl

def download_youtube_video(url):
    ydl_opts = {
        'format': 'bestvideo+bestaudio/best',
        'outtmpl': '%(title)s.%(ext)s',
    }
    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        try:
            info_dict = ydl.extract_info(url, download=True)
            video_title = info_dict.get('title', None)
            print(f"Downloaded '{video_title}' successfully!")
        except Exception as e:
            print("An error occurred during the download:")
            print(str(e))

video_url = 'https://www.youtube.com/watch?v=nWxB9yiYAgo'
download_youtube_video(video_url)

运行后返回错误：

ERROR: Unable to extract uploader id; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

我尝试调整代码结构，但问题依旧，请问我遗漏了什么？

核心原因 #

youtube-dl已经停止维护，YouTube页面结构更新后，旧版本的youtube-dl无法适配新的解析规则，导致提取上传者ID失败。

具体解决步骤 #

• 推荐方案：替换为yt-dlp（youtube-dl的活跃维护分支，持续适配YouTube的更新）

  1. 安装yt-dlp：

     pip install yt-dlp
     

  2. 修改代码，仅替换依赖库相关部分，其余逻辑不变：

     import yt_dlp
     
     def download_youtube_video(url):
         ydl_opts = {
             'format': 'bestvideo+bestaudio/best',
             'outtmpl': '%(title)s.%(ext)s',
         }
         with yt_dlp.YoutubeDL(ydl_opts) as ydl:
             try:
                 info_dict = ydl.extract_info(url, download=True)
                 video_title = info_dict.get('title', None)
                 print(f"Downloaded '{video_title}' successfully!")
             except Exception as e:
                 print("An error occurred during the download:")
                 print(str(e))
     
     video_url = 'https://www.youtube.com/watch?v=nWxB9yiYAgo'
     download_youtube_video(video_url)
     

• 备选方案：升级到youtube-dl开发版（不推荐）
  若坚持使用youtube-dl，可安装最新的开发版本，但后续仍可能因YouTube更新再次失效：

  pip install --upgrade git+https://github.com/ytdl-org/youtube-dl.git
