无法在Windows上加载RJB（Ruby Java Bridge）

Question

using

require 'rjb'

in IRB returns "true", but

require 'rjb'

in my application returns

cannot load such file -- rjb

Including 'rjb' into Gemfile does not solve the problem. What's wrong?

require "rubygems"

does not help.

rjb is installed.

I have Ruby 1.9.3

Answer 1

Edit Gemfile of your project in this way, add a string:

gem 'rjb', '1.4.7' <- put version of installed rjb gem

Then save Gemfile and do

bundle install

PS Sorry for my English =)

Answer 2

Depending on the version of Ruby you're using, you will require to load RubyGems first:

require "rubygems"
require "rjb"

You can check if rjb was installed as a gem using gem list rjb from a console.

Without more details about the version of Ruby you're using, guess this is the best I could answer it.
