macOS+Python3.12环境下PyTube访问streams触发AgeRestrictedError求助

针对macOS+Python3.12环境下，PyTube已设置use_oauth=True和allow_oauth_cache=True但仍触发AgeRestrictedError的问题，可按以下步骤排查解决：

• 清除OAuth缓存文件
  PyTube的缓存可能未正确保存认证状态，删除缓存后重新认证：

  rm ~/.pytube/oauth.json
  

  重新运行代码，跟随提示完成谷歌账号授权。

• 显式触发年龄验证逻辑
  在代码中主动调用bypass_age_gate()，确保认证会话被用于年龄验证请求：

  from pytube import YouTube
  
  yt = YouTube(
      "https://www.youtube.com/watch?v=G3e-cpL7ofc",
      use_oauth=True,
      allow_oauth_cache=True
  )
  yt.bypass_age_gate()
  print(yt.title)
  print(yt.streams)
  

• 升级PyTube至最新版本
  Python3.12兼容性可能在旧版PyTube中存在问题，执行升级：

  pip install --upgrade pytube
  

• 验证账号访问权限
  确保用于认证的谷歌账号在浏览器中可正常打开该年龄限制视频，排除账号本身无权限的情况。

使用代码：

from pytube import YouTube

yt = YouTube("https://www.youtube.com/watch?v=G3e-cpL7ofc", use_oauth=True, allow_oauth_cache=True)
print(yt.title)
print(yt.streams)
