pytube: 'NoneType' 对象没有属性 'span'
pytube: 'NoneType' object has no attribute 'span'
我尝试按照 pytube 示例从 YouTube 下载视频:
from pytube import YouTube
video = YouTube('https://www.youtube.com/watch?v=BATOxzbVNno')
video.streams.all()
并立即得到这个错误:

2 video = YouTube('https://www.youtube.com/watch?v=BATOxzbVNno')
----> 3 video.streams.all()

请帮助我。就在昨天还好好的!非常感谢!
我自己 运行 遇到了那个错误,尽管它得到了临时修复,但它似乎经常发生。
找到 github 的修复:NoneType object has no attribute 'span'
只需将函数 get_throttling_function_name 替换为:
