Hi,

Is there an easy way of finding the location of my installed gem
programmatically.
I need this to create an environment variable.

Thanks
Nasir

not in front of a computer but 'gem env | grep -i gempath' should come close
to working

C:\Documents and Settings\Usuario>irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> Gem.dir
=> "C:/Ruby/lib/ruby/gems/1.8"
irb(main):003:0>


HTH,

gem which gemname

e.g.

raggi@mbk:~$ gem which hpricot
(checking gem hpricot-0.6 for hpricot)
/opt/local/lib/ruby/gems/1.8/gems/hpricot-0.6/lib/hpricot.rb

Sure:

gem_spec = Gem::GemPathSearcher.new.find(require_name)
gem_dir = File.join(gem_spec.full_gem_path, gem_spec.require_path)

Hope that helps.
