Solution :1
Try in pytube/cipher.py on line 293:
You change
name = re.escape(get_throttling_function_name(js))
to
name = "iha"
Solution :2
you can also parser.py as
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.
and 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
