If in CentOS, Debian, Ubuntu, Windows etc. Please see archive of my blog’s already well this time I will explain how if at this time different from Fedora in Fedora enough to do the command yum yum and yum you already can get a version of Ruby and other Gems with the latest version, just go ahead.
Open a shell session you guys (terminal)
# yum update
to update the repository if you guys are still not up to date. install ruby
# yum install ruby
later you will give to the old stable version of ruby, that version of the old stable now 2.0, it’s already a version of ruby that could have compatibility with any application. then update its gems
# gem -v
Please go to the website of rubygems in https://rubygems.org/if the version on the OS you guys with in different site then do update
# gem update –system
Next, update the existing list of gem
# gem update
Note: If an error like this:
