Whenever I try to download a video, say this one Morbius Trailer, it throws the following error:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\Lenovo\AppData\Local\Programs\Python\Python310\lib\site-packages\pytube\__main__.py", line 181, in fmt_streams

    raise RegexMatchError(
pytube.exceptions.RegexMatchError: __init__: could not find match for ^\w+\W

During handling of the above exception, another exception occurred:

I can't find any solution for it, hope you can help!

Sorry to bother but I found a solution myself. It is a bug from the library itself. You need to follow the following steps:

  1. First go to C:\Users\\AppData\Local\Programs\Python\Python310\Lib\site-packages\pytube on Windows or pip find pytube and go to the location on Linux or Mac.
  2. Open the file cipher.py and edit Line 30 as: 
    var_regex = re.compile(r"^\$*\w+\W")

Now there will be no issues!

Defaulting to user installation because normal site-packages is not writeable Requirement already satisfied: pytube in c:\users\akhil\appdata\local\packages\pythonsoftwarefoundation.python.3.12_qbz5n2kfra8p0\localcache\local-packages\python312\site-packages `(15.0.0)```

IT WAS SHOWING LIKE THIS I HOPE U CAN HELP WITH THIS I'M NOT GETTING RUN THE CODE

You seem to have Python 3.12 in your system and pytube ( underlying dependency for this app ) doesn't support Python 3.12. See this
