Cannot load gem rack/test

Question

I'm trying to load `rack/test` into my application, but it's not working for some reason. When I do:

gem list rack-test

I get

rack-test (0.6.2)

So it's installed.

I can also get the path with:

gem which rack/test

which is

/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/gems/1.9.1/gems/rack-test-0.6.2/lib/rack/test.rb

But then

ruby -e 'puts $LOAD_PATH.inspect; $LOAD_PATH << "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/gems/1.9.1/gems/"; require "rack/test"'

yields

["/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/i686-linux", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/vendor_ruby/1.9.1", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/vendor_ruby/1.9.1/i686-linux", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/vendor_ruby", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1", "/home/jacky/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/i686-linux"]

What am I doing wrong?

Solved by reinstalling rvm. There was a superfluous ruby executable for some reason and it messed things up.
