Require 'green_shoes' -> ruby: no such file to load -- green_shoes (LoadError)

Sorry for this newbie’s question, but I’m stuck:

I installed the “green_shoes” gem on my Win7 PC (together with Ruby
1.8.7
that is) and everything looks fine at 1st glance: A “gem list” on the
cmd line results in this:

*** LOCAL GEMS ***

atk (1.0.0 x86-mingw32)
cairo (1.10.0 x86-mingw32)
columnize (0.3.4)
gdk_pixbuf2 (1.0.0 x86-mingw32)
glib2 (1.0.0 x86-mingw32)
green_shoes (0.255.0)
gtk2 (1.0.0 x86-mingw32)
linecache (0.46)
pango (1.0.0 x86-mingw32)
pkg-config (1.1.2)
rake (0.9.2)
rbx-require-relative (0.0.5)
ruby-debug (0.10.4)
ruby-debug-base (0.10.5.jb2 mswin32, 0.10.4)
ruby-debug-ide (0.4.17.beta5)
rubygems-update (1.8.7)

Now if I try to run a “hello world” like…

require ‘green_shoes’
Shoes.app( :width => 250, :height => 250 ) do
para ‘Hello, world!’
end

(stored in c:\temp\testshoe.rb )

…RM tells me that it can’t locate the gem:

c:\temp>irb -rgreen_shoes testshoe.rb
C:/Ruby187/lib/ruby/1.8/irb/init.rb:254:in require': no such file to load -- green_shoes (LoadError) from C:/Ruby187/lib/ruby/1.8/irb/init.rb:254:inload_modules’
from C:/Ruby187/lib/ruby/1.8/irb/init.rb:252:in each' from C:/Ruby187/lib/ruby/1.8/irb/init.rb:252:inload_modules’
from C:/Ruby187/lib/ruby/1.8/irb/init.rb:21:in setup' from C:/Ruby187/lib/ruby/1.8/irb.rb:54:instart’
from C:/Ruby187/bin/irb:13

Now the system DOES tell me that green_shoes is known, however:

c:\temp>gem which green_shoes
C:/Ruby187/lib/ruby/gems/1.8/gems/green_shoes-0.255.0/lib/green_shoes.rb

So I tried to hint it to the correct path:

c:\temp>set LOADPATH
loadpath=C:/Ruby187/lib/ruby/gems/1.8/gems/green_shoes-0.255.0/lib/

…but still to no avail. So what am I doing wrong??

Many thanks!

Try “irb -rubygems testshoe.rb” instead.

A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.

Also, note that Green Shoes is only compatible with Ruby 1.9.2. It
won’t work on 1.8.7.

@Steve: You saved my day! -> I installed 1.9.2 in parallel, switched
over with “pik” and voila, everything works as it should!
