I can also reinstall pytube using "pip install git+https://github.com/nficano/pytube.git" and also "pip install pytube". but the error is still now.

Solution

  • you can install :

    pip install pytube==11.0.1 or pip install --upgrade pytube

    or you can change in pytube/cipher.py :

    edit line:r'a\.[A-Z]&&\(b=a\.[sg]et\("n"\)\)&&\(b=([^(]+)\(b\),a\.[sg]et\("n",b\)\)}};'

    to

    r'a\.C&&\(b=a\.get\("n"\)\)&&\(b=([^(]+)\(b\),a\.set\("n",b\)\)}};',

    in the def get_throttling_function_name(js: str) -> str: function.
