Can't install jekyll gem at linux (classifier-reborn ruby version error)

Question

I'm working on ElementaryOS (linux) and this is what I have:

ruby -v
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]
rvm list
rvm rubies
   ruby-1.9.3-p551 [ x86_64 ]
=> ruby-2.2.0 [ x86_64 ]
which ruby
/home/ofcapl/.rvm/rubies/ruby-2.2.0/bin/ruby

And when I try to install jekyll gem I've got an error:

ERROR:  Error installing jekyll:
    classifier-reborn requires Ruby version >= 1.9.3.

I've tried to install it on ruby 2.2.0 and 1.9.3 but with no success.. Anyone know what to do?

Answer 1

I've found solution here

I've reinstalled rvm and rubygems without sudo and then installed jekyll gem without sudo.
