[gcfrxbots]

Also have this exact same error with the exact same log, tested on two different devices both running the newest version of Pytube. Worked perfectly fine yesterday.

This happens when I attempt YouTube(url)

Edit: In python 2.7.9

[ffabinhoo]

Same error here. Python 3.6

[j4tmr]

Same error occurs today. Does Youtube update its html content?

[hasan-dot]

Same error occurs today. Does Youtube update its html content?

yeah it seems like this @jhd4tmr and library Regex match should be updated

[ffabinhoo]

So do we have to wait for the update?

[minogame]

It looks like comment out the related part in codes as a temploary solution works for me.

# I'm not entirely sure what ``t`` represents. Looks to represent a # boolean. # t = regex_search( # r'\W[\'"]?t[\'"]?: ?[\'"](.+?)[\'"]', watch_html, # group=0, # ) params = OrderedDict([ ('video_id', video_id), ('el', '$el'), ('ps', 'default'), ('eurl', quote(watch_url)), ('hl', 'en_US'), # ('t', quote(t)), ])

Go to extract.py line 116 and change the following to look like:

    else:
        # I'm not entirely sure what ``t`` represents. Looks to represent a
        # boolean.
        #t = regex_search(
        #    r'\W[\'"]?t[\'"]?: ?[\'"](.+?)[\'"]', watch_html,
        #    group=0,
        #)
        params = OrderedDict([
            ('video_id', video_id),
            ('el', '$el'),
            ('ps', 'default'),
            ('eurl', quote(watch_url)),
            ('hl', 'en_US'),
            #('t', quote(t)),
        ])

Notice that we're just commenting out the stuff related to t. I don't know why this works, and I'm guessing there are other bad side-effects, but it got me through my needs for the day.

[ndg63276]

Yeah commenting out those lines seems to fix for me.

[DeeJayhX]

Same issue here. Python 3.7.2
@nficano can we get a pip upgrade pushed for this until the root cause is identified and corrected?

[RudreshVeerkhare]

Same error here...

It is worked, but waiting for official fix

[partriv]

same problem here,and @rriley's fix worked. waiting for new production release, but this works for now. Thanks Ryan!

[ulfgj]

quick and dirty :D works! tnx. hoping for an official fix soon.

[ghost]

Same error! Two days ago was working!

[maks-us]

Same error! Pytube 9.4.0
This comment temporary solved the issue. #381 (comment)

It looks like the html doesn't contain expected elements any more.

[ghwn]

Same error as well. Python 3.7.3 and Pytube 9.4.0

[BenjaminMWargo]

Same error on 3.7.3

Had the same problem earlier, about a week or more ago, some attempts were successful, though. Today, no luck at all.

[poohpeer]

Same for me 9.4.0. Python 3.7

Same for me 9.4.0. Python 3.5

[nanato12]

Hi, I can resolve this error.
because I'm Japanese, my english might be funny.
I use Mac only.

for MAC with Python3.7

try this command
ls -l /Library/Frameworks/Python.framework/Versions/3.7/etc/openssl/

if result is empty, try this command.
sudo /Applications/Python\ 3.7/Install\ Certificates.command

and, try it one time
ls -l /Library/Frameworks/Python.framework/Versions/3.7/etc/openssl/

[result]
total 8
lrwxr-xr-x 1 root admin 52 4 26 10:16 cert.pem -> ../../lib/python3.7/site-packages/certifi/cacert.pem

Please try it 😊😊

Cause
OpenSSL installed as standard on macOS is too old.
installers for macOS included OpenSSL with Python 3.6 or later.
OpenSSL of the system is not referenced.

As a result, the root certificate installed on the OS is also not referenced.
TLS server certificate validation fails.

[nanato12]

must do also this work.

Go to extract.py line 116 and change the following to look like:

Moreover, object like views,rating doesnt work

[lovavliet]

I had the same error as @walpolsh. After changing the extract.py the error disappears, but it is still not working. No I have the error:

I have python 3.7 installed and tried the things @nanato12 suggested. However it is still not working. Does anyone know what I should do?

u sure you commented out all these lines?

        # I'm not entirely sure what ``t`` represents. Looks to represent a

[wahyubram82]

No one try to debugging the script?
regex error means, the script try to read youtube source code and search a link to get the video source.

I'm affraid youtube make the link not shown before we do something, example click the play button.
need time to learn how this script working...

if the author answer what kind of link he search in youtube, maybe we can help him faster. if not we should do a debugging process, that mean try every step of script and see what the result to understood how this script working.

[nficano]

Hi folks, sorry for not being responsive here, I have become incredibly busy in recent months and haven't been able to support the project as much as I would like. Let me look into this now. I'll post an update for everyone shortly.

[nficano]

All fixed, fixed rating + views as well

[ulfgj]

[rola93]

All fixed, fixed rating + views as well

for me it was not that obvious, so I let it here just in case...

It's already merged in master, so pip install -U pytube to get the corrected version (9.5.0)

Thank you!

[zhangpeng0v0]

pip3 install -U pytube

great!!!
