I’m trying to use the XML builder package, but the require is not  
working.  
I have a hunch that I don’t have all the requisite dependencies  
installed,  
but what, I can’t figure out. Note, I’m a Ruby newbie.

I’ve tried the following on Fedora and CygWin after doing a “gem install  
builder” on both systems:

require ‘csv’  
require ‘builder’

xml = Builder::XmlMarkup.new( :target =\> “tmp.xml”, :indent =\> 2 )  
xml.instruct!(:xml, :version =\> “1.1”, :encoding =\> “UTF-8”)  
xml.declare!(:DOCTYPE, “beans”, :PUBLIC, “-//SPRING//DTD BEAN//EN”,  
“[http://www.springframework.org/dtd/spring-beans.dtd](http://www.springframework.org/dtd/spring-beans.dtd)”😉

xml.beans do  
CSV::Reader.parse(File.open(‘tmp.csv’, ‘rb’)) do |row|  
xml.loginId( row[1] ) if row[1] != nil  
end  
end

… and I just get: transform-csv.rb:11:in `require’: no such file to  
load  
– builder (LoadError)  
from transform-csv.rb:11

Have you tried:  
require ‘rubygems’  
require\_gem ‘builder’

Farrel,

OK, then I get  
/usr/lib/ruby/site\_ruby/1.8/rubygems.rb:204:in `report_activate_error': Could not find RubyGem builder (> 0.0.0) (Gem::LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:141:in`activate’  
from /usr/lib/ruby/site\_ruby/1.8/rubygems.rb:37:in  
`require_gem_with_options' from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:31:in`require\_gem’  
from transform-csv.rb:12

Only use require\_gem if you need a specific gem version ? and if you  
do you still need to ?require “the\_gem\_lib”?. I think require\_gem is  
now named activate\_gem to help lessen the confusion.

To get it to work:

require “rubygems”  
require “builder”

Sorry, I posted too fast. The it works now on Fedora but not on CygWin,  
so I’m just somehow missing this “RubyGem builder” thingy on CygWin.

Daniel,

Yes, your simpler require’s work on Fedora as well, but CygWin _still_  
cannot resolve the dependencies (I get the same error).

Sorry, to clarify, on CygWin, if I do:

require ‘rubygems’  
require ‘csv’  
require ‘builder’

… I get …

/usr/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:21:in  
`require__': no such file to load -- builder (LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in`require’  
from transform-csv.rb:9

… but if I do:

require ‘rubygems’  
require ‘csv’  
require\_gem ‘builder’

… I get instead …

/usr/lib/ruby/site\_ruby/1.8/rubygems.rb:204:in `report_activate_error': Could not find RubyGem builder (> 0.0.0) (Gem::LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:141:in`activate’

`require_gem_with_options' from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:31:in`require\_gem’  
from transform-csv.rb:9

_both_ versions work OK on Linux/Fedora.
