The version of Ruby required by this gem. The ruby version can be specified to the patch-level:
$ ruby -v -e 'p Gem.ruby_version' ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0] #<Gem::Version "2.0.0.247">
Because patch-level is taken into account, be very careful specifying using ‘<=`: `<= 2.2.2` will not match any patch-level of 2.2.2 after the `p0` release. It is much safer to specify `< 2.2.3` instead
Usage:
# This gem will work with 1.8.6 or greater... spec.required_ruby_version = '>= 1.8.6' # Only with ruby 2.0.x spec.required_ruby_version = '~> 2.0' # Only with ruby between 2.2.0 and 2.2.2 spec.required_ruby_version = ['>= 2.2.0', '< 2.2.3']
