Please confirm that you are on the latest version of pytube by installing from the source.

You can do this by running python -m pip install git+https://github.com/pytube/pytube Sometimes, the pypi library repository is not up to date, and your issue may have been fixed already!

In C:\Python38\lib\site-packages\pytube\cipher.py

Change this line:

293: name = re.escape(get_throttling_function_name(js))

to this:

293: name = "iha"

this Solution is mentioned in Github issues and it's working fine.

Here is an example:

from pytube import YouTube
import os
from pathlib import Path


url = YouTube('https://www.youtube.com/watch?v=y-9MaAW_9dY')

print("downloading....")

video = url.streams.get_highest_resolution()

path_to_download_folder = str(os.path.join(Path.home(), "Downloads"))

video.download(path_to_download_folder)
print("Downloaded! :)")
