When trying to install a local gem with jgem (jruby-9000) with requirement for at least 2.0.0 ruby version install fails not reqd version level. However jruby -S gem for same gem works fine.

Could you tell us what gem it is? JRuby 9000 should report RUBY_VERSION as 2.2 and pass any 2.0.0 requirements easily.

@headius headius added this to the 9.0.0.0.rc1 milestone Apr 17, 2015

The gem was one of my own jruby_art, but it is available as from rubygems gem install jruby-art --pre. To be clear I was using both jruby and jgem from the build directory (fully qualified path to jruby 9000).
jgem --version 2.1.9
jruby --version jruby 9.0.0.0-SNAPSHOT (2.2.1) 2015-04-15 7e4e64f OpenJDK 64-Bit Server VM 25.40-b23 on 1.8.0_40-b20 +jit [linux-amd64]

The following appears to work correctly on master (to be 9k.rc2) so I'm going to call this fixed. This code mimics RubyGems' own logic for checking Ruby versions.

If you still have the problem, please provide a gem that fails to install against JRuby master (or 9k.rc1) so we can reproduce the issue.

$ jruby -e "p Gem::Requirement.create('>=2.0.0').satisfied_by? Gem.ruby_version"
true
