I’m using Mac OSX 10.6.3
with jruby 1.5.0 (ruby 1.8.7 patchlevel 249)

jirb work, jgem work

When

jruby -S gem install rails
Successfully installed rails-2.3.8
1 gem installed
Installing ri documentation for rails-2.3.8…

Look like jruby can’t find rails. Any suggestion please ?

What does which rails show? Or jruby -S gem list --local ?

It looks to me to be an rvm problem; is there a mailing list for that?

Yep, those kind of errors are usually caused because GEM_PATH or
GEM_HOME
are set, and rvm does it for you.

Run jruby -S gem env to ensure everything is right.

I think my rvm did not set them.

But take a closer look at the output you’ve provided:

  • GEM PATHS:
    • /Users/cyberjom/.rvm/gems/jruby-1.5.0
    • /Users/cyberjom/.rvm/gems/jruby-1.5.0@global

So, rvm does this.

I have navigate to those GEM PATHS and can see those gem files ?

Any suggestion please. I will try install everything again…

Try cutting off the middle man, rvm. Also, see what ‘which jruby’
returns. If it’s not running from your rvm install, it won’t see gems
installed inside ~/.rvm.

I suppose the problem is that gem is not well configured, look at these
variables:

  • RUBY EXECUTABLE: /Users/cyberjom/.rvm/rubies/jruby-1.5.0/bin/jruby

WHERE THE JRUBY EXECUTABLE IS

  • EXECUTABLE DIRECTORY: /Users/cyberjom/.rvm/gems/jruby-1.5.0/bin

WHERE THE EXECUTABLE ARE

So, when rails is installed via “jruby -S gem install rails” the rails
executable is placed into the EXECUTABLE_DIRECTORY path, but when you
call
“jruby -S rails” jruby is probably searching into its own executable
directory, I mean “/Users/cyberjom/.rvm/rubies/jruby-1.5.0/bin”.

Could you point this into the rvm mail list? perhaps they have a better
answer.

Yeh… Thank you very much. After weeks , finally with all your
suggestion.
I tried reinstall latest version of RVM and now it’s work.

I can start a simple rails project with jruby 1.5.1

May be because of mis-config rvm…

I will try warbler , postgrese jdbc and oracle jdbc tomorrow.

Thank every one.
