Hi all,

I tried to install yt using the All-in-One Installation Script. I'm
using Ubuntu 14.04, and I have installed the required packeges listed
at the beginning of the script.

All the installation process went fine, then I sourced the activation
script in a new shell, and to check if everything was fine, I typed yt
--help, and this is the output:

Traceback (most recent call last):

I tried different configurations, such as installing the stable and
the yt branch, turn on/off the scipy installation flag in
install_script.sh, but nothing.

Please, do you have any suggestions?



Thanks in advance,
Andrea
