I am running cygwin with ruby version ruby 1.8.7 (2008-08-11 patchlevel
72) [i386-cygwin]

When I installed zipruby I noticed this:

make install
mkdir -p /usr/lib/ruby/gems/1.8/gems/gems/gems/zipruby-0.2.9/lib
/usr/bin/install -c -m 0755 zipruby.so
/usr/lib/ruby/gems/1.8/gems/gems/gems/zipruby-0.2.9/lib

Why do I have three gems subdirs? And where should all my gems be
centrally located and what should $GEM_HOME be? I would think it would
be one location for my situation...my home laptop used for ruby coding
for my night work apart from my full time job.

Also: I installed rubygems, but I am still seeing this below"

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'zip/zip'
=> true
irb(main):003:0> require 'rubygems'
=> false
irb(main):004:0>

Smith@smith-laptop /usr/lib/ruby/gems/1.8/gems
$ gem list --local

Smith@smith-laptop /usr/lib/ruby/gems/1.8/gems
$ echo $GEM_HOME

thank you!

I don't see a problem with having gems/gems/gems as long as all your gems
are there.
Also the behavior you are seeing in irb is perfectly normal. false just
means it didn't load rubygems (because it has already been loaded) it
doesn't mean there was an error, or that the load failed.

Typically it isn't set:

$ echo $GEM_HOME

Ooops...meant to say rubyzip:

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'rubyzip'
LoadError: no such file to load -- rubyzip
from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'
from
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from (irb):2
irb(main):003:0>

$ gem list --local
