Hi, everybody,

i need some help and I'm pretty a newbie so be patient with me please :-)

Now the issue
I'm trying to develop a web site and I decided for Omega4 as theming toolkit.
I installed the gems componend with bundler and everything was working good.
Then I decided to try "susy" but version 2 instead of the default, which is the version 1.

To do that I update to the higher version with
gem install susy

then I modified the gemfile of my subtheme
gem 'susy', '>= 2.1.2'

then I updated the bundler
bundle update

Everything seems to be fine and the susy version is set to the 2nd
Good, now I try to run omega-guard foe my sub theme with
drush omega-guard

and after selecting the subtheme a lot of errors.
Here below the all set:
