so my issue is I run this simple code to attempt to make a pytube stream object...
from pytube import YouTube
yt = YouTube('https://www.youtube.com/watch?v=aQNrG7ag2G4')
stream = yt.streams.filter(file_extension='mp4')
And end up with the error in the title.
full error:
Traceback (most recent call last):
File ".\test.py", line 4, in <module>
stream = yt.streams.filter(file_extension='mp4')

As juanchosaravia suggested on https://github.com/pytube/pytube/issues/1199, in order to solve the problem, you should go in the cipher.py file and replace the line 30, which is:
var_regex = re.compile(r"^\w+\W")
With that line:
var_regex = re.compile(r"^\$*\w+\W")
After that, it worked again.
