JRuby 1.6.0RC1 - Rails 3 in 1.9 mode

Ruby JRuby

Hello,

I’m trying to do this:

jruby --1.9 --server -S bundle exec rails s

It always runs as 1.8.7 instead of 1.9.2

If I do:

jruby --1.9 --server -S rails s

it fails with

org/jruby/RubyModule.java:2528:in const_missing': uninitialized constant Bundler (NameError) from /Users/robertrouse/work/project/config/boot.rb:7:in(root)’
from org/jruby/RubyKernel.java:1047:in require19' from script/rails:5:in(root)’

Any idea what I’m doing wrong here?

Thanks!

Do you know if the gems installed were installed for 1.8 or 1.9 JRuby?

when I run

jruby --1.9 -S rails s

I get a gem not found error: `report_activate_error’: Could not find
RubyGem
rails (>= 0)

So, I installed the gems with 1.9:

jruby --1.9 -S gem install rails

and I was a happy camper.

Clarifying further:

PS C:\mydocs> jruby -S gem env
RubyGems Environment:

  • RUBYGEMS VERSION: 1.5.0
  • RUBY VERSION: 1.8.7 (2011-01-10 patchlevel 330) [java]
  • INSTALLATION DIRECTORY: C:/jruby-1.6.0.RC1/lib/ruby/gems/1.8
  • RUBY EXECUTABLE: C:/jruby-1.6.0.RC1/bin/jruby.exe
    …
  • GEM PATHS:
    • C:/jruby-1.6.0.RC1/lib/ruby/gems/1.8
    • C:/mydocs/.gem/jruby/1.8
      …

PS C:\mydocs> jruby --1.9 -S gem env
RubyGems Environment:

  • RUBYGEMS VERSION: 1.5.0
  • RUBY VERSION: 1.9.2 (2011-01-10 patchlevel 136) [java]

1.9 gems have a different location than 1.8 gems.

Actually,

I’m running this under RVM, so the gem path would be the same. When I do
jruby --1.9 -S gem list, I see all the gems I installed.

Unfortunately, RVM is outside of my knowledge. I’m stuck on WinXP for
the
time being, so RVM is not something I can leverage.

Ah, that makes sense. I would have run it in 1.8 mode.

Thanks.

if you have (or want) multiple rubies installed on your WinXP, take a
look into GitHub - vertiginous/pik: Ruby version manager for Windows
