I just downloaded pytube (version 11.0.1) and started with this code snippet from here:
from pytube import YouTube
YouTube('https://youtu.be/9bZkp7q19f0').streams.first().download()
which gives this error:
AttributeError Traceback (most recent call last)

and I wonder why? Can anyone help me? I am running this snippet in an ipython console (IPython version 7.22.0) with Python 3.8.8 in a conda environment.
Found this issue, pytube v11.0.1. It's a little late for me, but if no one has submitted a fix tomorrow I'll check it out.
in C:\Python38\lib\site-packages\pytube\parser.py
Change this line:
152: func_regex = re.compile(r"function\([^)]+\)")
to this:
152: func_regex = re.compile(r"function\([^)]?\)")
The issue is that the regex expects a function with an argument, but I guess youtube added some src that includes non-paramterized functions.
I had the same problem, I changed parser.py as in the answer above, just forked pytube lib on GitHub, and changed the file.
You can install pytube this way:
pip install git+https://github.com/baxterisme/pytube
Instead of:
pip install pytube
The most simplest solution can be:
The problematic version was 11.0.1 and now has already been fixed, so you just need to upgrade to the newer version, and will be working fine again:
pip install --upgrade pytube
Edit:
I have tried to keep my solution up to date but I started to feel that pytube appears to have problems frequently and these bugs detrimentally affect my project. So I refactored it and started to use ytdlp library from now on. So at the time you are reading this, this solution might not work for you.
For the time being as we got this error again. You can try solution given here
Or
Make sure you in pytube/cipher.py on line 293:
You change
name = re.escape(get_throttling_function_name(js))
to
name = "hha"
