pytube.exceptions.RegexMatchError：__init__：找不到 ^\w+\W 的匹配项

Question

所以我的问题是我运行这个简单的代码来尝试创建一个 pytube 流对象......

from pytube import YouTube

yt = YouTube('https://www.youtube.com/watch?v=aQNrG7ag2G4')
stream = yt.streams.filter(file_extension='mp4')

并最终出现标题中的错误。

完整错误：

Traceback (most recent call last):
  File ".\test.py", line 4, in <module>
    stream = yt.streams.filter(file_extension='mp4')
  File "C:\Users\logan\AppData\Local\Programs\Python\Python38\lib\site-packages\pytube\__main__.py", line 292, in streams       
    return StreamQuery(self.fmt_streams)
  File "C:\Users\logan\AppData\Local\Programs\Python\Python38\lib\site-packages\pytube\__main__.py", line 184, in fmt_streams   
    extract.apply_signature(stream_manifest, self.vid_info, self.js)
  File "C:\Users\logan\AppData\Local\Programs\Python\Python38\lib\site-packages\pytube\extract.py", line 409, in apply_signature
    cipher = Cipher(js=js)
  File "C:\Users\logan\AppData\Local\Programs\Python\Python38\lib\site-packages\pytube\cipher.py", line 33, in __init__
    raise RegexMatchError(
pytube.exceptions.RegexMatchError: __init__: could not find match for ^\w+\W

额外数据：

python版本：3.8.10 pytube版本：11.0.2

Answer 1

正如 juanchosaravia 在https://github.com/pytube/pytube/issues/1199上建议的那样，为了解决该问题，您应该进入 cipher.py 文件并替换第 30 行，即：

var_regex = re.compile(r"^\w+\W")

用那行：

var_regex = re.compile(r"^\$*\w+\W")

之后，它又起作用了。
