Can not install jekyll and its Runtime Dependencies

I'm not a programmer but love to work with jekyll and markdown.

I've installed and used jekyll on many Linux distros (mostly debian flavours though).

Now I'm on Opensuse 13.1 which is a wonderfull solid Linux Distro.

Anyways, My problem is that I simply can not install jekyll and its Runtime Dependencies. I've tried all possible solutions (I think) and now I'm lost.

This is the output when trying to install classifier.

>> sudo gem install classifier  
sudo gem install classifier
root's password:
ERROR:  Could not find a valid gem 'classifier' (>= 0), here is why:  
          Unable to download data from https://rubygems.org - no such name (https://api.rubygems.org/latest_specs.4.8.gz)  

ERROR:  Possible alternatives: classifier

Any advise ??

I've installed all the devel libraries with:

>> sudo zypper in -t pattern devel_basis

And updated the ruby-gems with:

>> sudo gem update --system --source http://rubygems.org  

>> gem -v
2.2.2

Below some info that could be usefull for troubleshooting:

>> ruby -v  
ruby 2.0.0p247 (2013-06-27) [x86_64-linux]

ruby-devel 2.0-5.1.2

>> gem env

Solution

I did get it sorted out.

The solution for me was to write this in a terminal
sudo update_rubygems

And then
sudo gem install jekyll

Now it works :-)
