昨天这个程序运行得很好，但今天我却出了那个错误
这就是程序：

from pytube import YouTube

url = input("Give link: ")
video = YouTube(url)

video_audio = video.streams.get_audio_only()

video_audio.download(filename_prefix="Audio ")

这是错误的：

Traceback (most recent call last):
  File "C:\Users\Admin\Desktop\Python\YTDowlander.py", line 8, in <module>
    video_audio = video.streams.get_audio_only()

    self.throttling_plan = get_throttling_plan(js)

    transform_plan_raw = find_object_from_startpoint(raw_code, match.span()[1] - 1)
AttributeError: 'NoneType' object has no attribute 'span'

我只更新了pytube中的cipher.py，因为新的youtube链接
