Latest Version of youtube-dl gives Python errors

[eddmy]

Upgrading with
$ youtube-dl -U
breakes something...
$ youtube-dl

Do I have to upgrade Python ?

Can you post the output you get when add the -v option? youtube-dl works fine for me.

[eddmy]

Since it crashes it doesn't matter what you write after "youtube-dl". The
output is always the same.

Ok, then we're going to have to do this by hand:

• What operating system and architecture are you on? Can you describe the distribution?
• What is your Python library? What does python --version output? How did you procure Python?
• What version of youtube-dl are you using, i.e. how did you update it last, and what is the md5sum of the file?

With these additions, we should be able to reproduce the problem, and then fix it or find a workaround. Note that a similar error was reported, but for Python 2.7.0, which should no longer be in use anywhere, since it contains significant bugs such as this one and has security vulnerabilities.

Open Suse 11.4 / 64 bit Intel

python --version
Python 2.7

YAST sais: 2.7-9.40.1 (x86_64)

youtube-dl was updated 2014-Nov-18 using youtube-dl -U

md5sum /usr/bin/youtube-dl
03ee1c60475c9eb4684eea8639606e2e /usr/bin/youtube-dl

Thanks

I installed Python 3.1.3 and changed the symbolic link so that the command works
$ python --version
Python 3.1.3

New error message is now
$ youtube-dl https://www.youtube.com/watch?v=jzkUUSWiM_4

Sorry for the needless trouble, but 3.1.3 never has been and is not supported by youtube-dl. It requires 3.3+ or a recent 2.6 or 2.7.

[eddmy]

Recent ???
OK, I downgraded Python and youtube-dl again, so the error message is pretty downgraded as well.
:-)

Back to square one - obviously.

@eddmy Slight quiproquo it seems. @phihag meant a recent 2.7.x version, like 2.7.8 (see Downloads).

Just tested with 2.7.8, works fine.

[phihag]

Installing OpenSuse 11.04, I have found to be their Python version the horribly outdated 2.7.0.

Thank you for the report! Fixed in youtube-dl 2014.11.20. See our FAQ if you have problems updating.
