Pytube: getting regex error

[waterholic]

Upon downloading a playlist, i get the regex error
Exception in Tkinter callback Traceback (most recent call last): File "C:\Python34\lib\tkinter\__init__.py", line 1487, in __call__ return self.func(*args) File "C:/Users/nicto/PycharmProjects/idk/playlist activator/playlist downloader.py", line 40, in func pl.download_all('C:\\pythonpractice\music') File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\contrib\playlist.py", line 150, in download_all yt = YouTube(link) File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\__main__.py", line 88, in __init__ self.prefetch_init() File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\__main__.py", line 97, in prefetch_init self.init() File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\__main__.py", line 133, in init mixins.apply_signature(self.player_config_args, fmt, self.js) File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\mixins.py", line 49, in apply_signature signature = cipher.get_signature(js, stream['s']) File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\cipher.py", line 250, in get_signature tplan = get_transform_plan(js) File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\cipher.py", line 69, in get_transform_plan name = re.escape(get_initial_function_name(js)) File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\cipher.py", line 45, in get_initial_function_name return regex_search(pattern, js, group=1) File "C:\Users\nicto\PycharmProjects\idk\venv\lib\site-packages\pytube\helpers.py", line 41, in regex_search .format(pattern=p), pytube.exceptions.RegexMatchError: regex pattern (yt\.akamaized\.net/\)\s*\|\|\s*.*?\s*c\s*&&\s*d\.set\([^,]+\s*,\s*(?P<sig>[a-zA-Z0-9$]+)\() had zero matches

[ytensor42]

yeah, I am experiencing same error since few hours ago.
google may have changed their regex pattern again.
I downloaded the latest changes from this repo and have same error.

[peterrenshaw]

same problem, py3.5, re-installed with latest pytube, get this with valid code:

Same error but it occurs intermittently

[Sinkler]

yes, we have the same problem with this video https://youtu.be/zGpVuknnN78?t=60

[billd100]

Experienced same error. In cipher.py replace the regexs in pattern in get_initial_function_name with:
r'\bc\s*&&\s*d\.set\([^,]+\s*,\s*\([^)]*\)\s*\(\s*(?P<sig>[a-zA-Z0-9$]+)\('.

[ytensor42]

Experienced same error. In cipher.py replace the regexs in pattern in get_initial_function_name with:
r'\bc\s*&&\s*d\.set\([^,]+\s*,\s*\([^)]*\)\s*\(\s*(?P<sig>[a-zA-Z0-9$]+)\('.

This change seems working ok. Thanks!

[yelosheng]

Same error.

[billd100]

@yelosheng It doesn't look like you updated your regex. See my comment above or pull the most recent version of the lib.

FYI if you want to install the latest source directly from github using pip, type this in your command line:

pip install git+https://github.com/nficano/pytube.git

[amitoo7]

pip install git+https://github.com/nficano/pytube.git
This one is works fine
Thanks,

I'm also using pytube 9.3.5 but with Python 3.7. I change in the cypher.py file and works great

[se681268]

I'll try 3.7. Thank you @JakLeg

[vassiliskrikonis]

I experienced the error in #336 and 9.3.6 solves this issue. Any idea when it is going to be available through pip without pointing to the git repo (although I know that you can have git repos in the requirements.txt)

[Taein0910]

I think this error appears in a copyrighted video.

[thiagodeschamps]

I did what he said and I can download all the videos, even that you posted (Paint It Black Video). Check it out https://youtu.be/Ufw5KbcT3OU

[adhoc92]

I did what he said and I can download all the videos, even that you posted (Paint It Black Video). Check it out https://youtu.be/Ufw5KbcT3OU

It's actually working for me since I replaced the text in the Cypher file. I thought for sure I deleted my post, but somehow people are still seeing it.
