hallo!

i’m unable to use “require ‘rjb’” successfully, although rjb appears  
to have installed successfully.

i am using ruby 1.8.6, irb 0.9.5, java 1.5.0, rjb 1.1.2, and os x  
10.5.2.

i was able to use the require line just fine via irb:

gir:dev$ which irb  
/usr/bin/irb

gir:dev$ irb --version  
irb 0.9.5(05/04/13)

gir:dev$ irb

> > require ‘rjb’  
> > =\> true
> 
> > require ‘net/smtp’  
> > =\> true  
> > […]

but i was unable to run the ‘require’ line from within my own test  
script:

gir:dev$ cat ./test.rb  
#!/usr/bin/env ruby

require ‘rjb’

puts ‘is this working?’

gir:dev$ ./test.rb  
./test.rb:3:in `require’: no such file to load – rjb  
(LoadError)from ./test.rb:3

i run ‘gem list rjb’ and ‘gem content rjb’, and rjb appears to be  
installed:

gir$ gem list rjb  
\*\*\* LOCAL GEMS \*\*\*

rjb (1.1.2, 1.1.1)

gir$ gem content rjb

i see the ‘test.rb’ file so i try to run that, to no avail:

gir$ sudo /Library/Ruby/Gems/1.8/gems/rjb-1.1.2/test/test.rb  
/Library/Ruby/Gems/1.8/gems/rjb-1.1.2/test/test.rb:5:in `require’: no  
such file to load – rjb (LoadError)  
from /Library/Ruby/Gems/1.8/gems/rjb-1.1.2/test/test.rb:5

note i replaced the first line’s ‘local’ to ‘bin’ (otherwise  
interpreter doesn’t exist):

gir$ head test.rb  
#!/usr/bin/env ruby

# $Id: test.rb 58 2008-01-14 08:25:07Z kuwa1 $

require ‘test/unit’  
require ‘rjb’

puts “start RJB(#{Rjb::VERSION}) test”  
class TestRjb \< Test::Unit::TestCase  
include Rjb  
def setup  
[…]

eek! what am i overlooking? please advise.

Does require ‘rubygems’ before require ‘rjb’ fix it?
