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

Question

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: 'NoneType' object has no attribute 'span'

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.

Honestly, this might have been broken by changes with YouTube. Just speculation though. I get the exact same issue. — hyperneutrino

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 am too lazy but I guess this should be reported on github to inform the developers about it.

Braynstorm Over a year ago

actually, even better would be function\([^)]*?\)

Yalchin Mammadli Over a year ago

It was working yesterday, now it's not working again, at least on my side, I checked line 152, it's okay, however, it's again throwing me the same error...

Matt Over a year ago

Yalchin, I just had this issue again after having fixed it this way as well. I put it back to how it was originally and it is now working again. I suspect it was an interim change at youtube.

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"

Thanks Jeffery Williams

After applying the parser.py avobe mention patches with no success, this worked for me. Finger cross and see how long it lasts!

none of the other answers worked, but this one does

For me, nothing worked except a fresh uninstall-installation of pytube.

Yalchin Mammadli Over a year ago

Solution above is outdated as I mentioned in the edit.

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 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

The most simplest solution can be:

Go to the location where your python is installed (Mainly in : C:/Users/HP/appdata/local/programs/python)
Search for pytube in the top right corner and delete all the pytube modules you see
open your cmd (in administrative mode) here
enter the command : pip install pytube
it's done ✅ Now try running the code again [ ⭐I had the same issue and these steps solved it]
