pytube: [BUG] RegexMatchError ?

I just updated the regex like this and it’s working: ^\$*\w+\W

I’m able to download the videos again.

Nope, i shifted my project to ytdlp ( ytdl forked, more advanced and get frequently updates ) . I got sick of pytube and its bugs on daily basis, my project got affected very bad with pytube. Now i am happy with more reliable and powerful lib ytdlp. Again i am not saying pytube is bad lib, But due to lack of updates by author and tons of bugs which is not getting fixed by months , i just shifted also i advise you same whosoever is running their project with pytube.

Thanks , this is not hate message for pytube, its just a my recommendation.

Prolly some new changes from youtube side

what worked for me was: in pytube/cipher.py change the line: var_regex = re.compile(r"^\w+\W") to var_regex = re.compile(r"^\$*\w+\W")

I just updated the regex like this and it’s working: ^\$*\w+\W

I’m able to download the videos again.

Thank you Juancho, I add this fix to PR #1193

Hi, anyone who’s using this library on some cloud-based platform like heroku can use my temporary repository till the next update. just in requirements.txt file replace pytube with git+https://github.com/ehsanbehdad/Pytube then you’ll be fine.

Sure it works perfectly, I tested it locally, but what if the app is deployed on Streamlit Cloud/sharing, Heroku … ?

Same. Raise exception from here: https://github.com/pytube/pytube/blob/master/pytube/cipher.py#L31 The code for js changed. Reviewing the regular expression is a good start point.

What text editor is this @JavDomGom

top screenshot at least looks like PyCharm

HUGE you guys rock. Can’t wait for the patch

Yes, there are many PR to review and merge. As soon as the original code is up to date we should all update as well. Temporarily, whoever wants can use my fork with these problems already solved and if you prefer you can also apply the changes to your local version.

I wrote the code to fix this bug in this PR https://github.com/pytube/pytube/pull/1336 I tested it locally and it worked for me. Until this PR gets merged you can manually edit the cipher file on line 30 and change the regular exp as mentioned in this stack overflow answer https://stackoverflow.com/a/70777385

Some guy showed this image. Which file is that, and where can i access it

@JavDomGom please add another change to your PR:

# pytube/parser.py, line 152
-    func_regex = re.compile(r"function\([^)]+\)")
+    func_regex = re.compile(r"function\([^)]*\)")

this fixes another exception occurring during audio fetching:
