Using pytube on PyCharm

I have a script, which has been working fine in April 2021 when I created it, but now it gives me the following error. I'm not very experienced in coding, so if anyone can help me it would be great.

What I'm trying to do is simply download a song from youtube as a mp4. I can see that the error says there is something wrong with the pytube module imported, but I am not skilled enough to see what it is.

I'm using MacOS 12.1, Pycharm 2020.3, and Python 3.9.

Script:

import pytube

url = str('https://www.youtube.com/watch?v=gJLIiF15wjQ')
youtube = pytube.YouTube(url)
video = youtube.streams.get_by_itag(140)
video.download(output_path='/Users/clarajacobsen/Documents/TrueFIR/Klub100/Songs/', filename='test')

Error:

After trying out solution 1, suggested by Sarim, error in PyCharm:

Traceback (most recent call last):

    raise RegexMatchError(caller="regex_search", pattern=pattern)
pytube.exceptions.RegexMatchError: regex_search: could not find match for iha=function\(\w\){[a-z=\.\(\"\)]*;(.*);(?:.+)}

During handling of the above exception, another exception occurred:

After trying to run it in Google Colab:

/usr/local/lib/python3.7/dist-packages/pytube/cipher.py in get_throttling_function_code(js)
    299 
    300     # Extract the code within curly braces for the function itself, and merge any split lines
--> 301     code_lines_list = find_object_from_startpoint(js, match.span()[1]).split('\n')
    302     joined_lines = "".join(code_lines_list)
    303 

AttributeError: 'NoneType' object has no attribute 'span'
Solution

  • To fix this issue, This doesnt depends on which operating system you are on or which python you are using. Follow these steps:

    1. I used Colab for this, if you are using Google colab use it and test it.
    2. Install Pytube with !pip install pytube
    3. After installing pytube just shutdown the kernel and the application you are using for it. either VSCode, Jupyter notebook or Colab. shut down its kernel.
    4. Then run the enviroment again and try importing and running your code.
    5. It should run now.

    or if it gives you the same error as before:

    1. Go to the files where pytube is install and go to folder in pytube named "pytube" then go into "cipher.py" and open it.
    2. Search for the line: 293. Where name = re.escape(get_throttling_function_name(js))
    3. Replace name = "iha"
    4. Then close all kernels and file you are running the code on. and restart them completely after shutting down.

    These two solutions should work 100%. Solution that worked for me is first one.
