python - Pytube 库 - 尝试访问视频数据时收到 "pytube.exceptions.RegexMatchError: regex pattern"错误

Question

当尝试使用 pytube API 库访问 Youtube 视频的“标题”等数据时，我收到以下错误

pytube.exceptions.RegexMatchError: regex pattern (yt.akamaized.net/)\s*\|\|\s*.?\sc\s*&&\sd.set([^,]+\s,\s*(?P[a-zA-Z0-9$]+)() had zero matches

这是我正在使用的代码，它提供了上述错误。

import sys  
import pytube

link = input('Enter url: ') # url is: https://www.youtube.com/watch?v=KSbj-cFtFPA
yt = pytube.YouTube(link)
print(yt.title)

sys.exit()

有人知道如何解决这个错误吗？我已经进行了一些在线搜索，提供的答案并不明确，并且当我尝试时不起作用。

注意:我尝试卸载 pytube 并重新安装它，但这并没有解决问题。

这是对该问题的后续答复。我根据文档添加了一些错误处理来告诉您发生了什么。

- Video 1 in the list will throw an extraction error. because the video has been removed from YouTube

- Video 2 in the list will throw an unavailable error. because the video does not exist on YouTube

- Video 3 in the list will display the correct title info, because the video exists on YouTube.

video_lists = ['https://www.youtube.com/watch?v=KSbjcFtFPA',
           'https://www.youtube.com/watch?v=MEEJOZkmIxvU',
           'https://www.youtube.com/watch?v=MEEJOZkmIxU'
           ]

for video in video_lists:

  try:
    yt = pytube.YouTube(video)
    print (yt.title)

  #################################################################
  # This one should catch - pytube.exceptions.RegexMatchError:
  # regex pattern ((?:v=|\/)([0-9A-Za-z_-]{11}).*) had zero matches
  #################################################################
  except pytube.exceptions.RegexMatchError:
    print('The Regex pattern did not return any matches for the video: {}'.format(video))

  except pytube.exceptions.ExtractError:
    print ('An extraction error occurred for the video: {}'.format(video))

  except pytube.exceptions.VideoUnavailable:
    print('The following video is unavailable: {}'.format(video))

**OUTPUTS**
An extraction occurred for the video: https://www.youtube.com/watch?v=KSbjcFtFPA

The following video is unavailable: https://www.youtube.com/watch?v=MEEJOZkmIxvU
