python中的pytube.exceptions.RegexMatchError

Question

我可以尝试找到不同格式的youtube视频。正在使用pytube流筛选器，但它给出了一个错误pytube.exceptions.RegexMatchError

from pytube import YouTube

url = input('Enter url :')

link = YouTube(url)

print(link.title)

obj = link.streams.filter(progressive="True")
print(obj)

以下给出了此错误：

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

我还可以使用“pip-install-git”重新安装pytube+https://github.com/nficano/pytube.git“以及”pip安装pytube”。但错误仍然存在

Answer 1

您可以安装：

pip install pytube==11.0.1 or pip install  upgrade pytube

或者您可以在pytube/cipher.py中更改：

edit line:r'a\.[A-Z]&&\(b=a\.[sg]et\("n"\)\)&&\(b=([^(]+)\(b\),a\.[sg]et\("n",b\)\)}};' 

到

r'a\.C&&\(b=a\.get\("n"\)\)&&\(b=([^(]+)\(b\),a\.set\("n",b\)\)}};',

在def get_throttling_函数中\u name（js:str）->；str:函数
