yuotube.dl not starting

[Hugo-Eduardo]

Hi, I downloaded manually youtube.dl (2014.10..30) in my Fedora 14, and try to run, but got following error (with or without parameters) Tried many times, always the same.
[root@localhost Downloads]# youtube-dl -h
Traceback (most recent call last):

TypeError: invalid arguments

Any hint?

Thanks

Unfortunately, that seems to be a bug which was fixed in python 2.7.1. Can you upgrade your python version and try again?
If it still fails, please post the output of /usr/bin/env python --version.
