rubygem Проблемы с Twitter4R

Question

Я пытаюсь начать работу с twitter4r, но у меня возникают некоторые проблемы:

Почему я не могу загрузить гем в IRB?

$ sudo gem install twitter4r
Successfully installed twitter4r-0.3.2
1 gem installed
Installing ri documentation for twitter4r-0.3.2...
Installing RDoc documentation for twitter4r-0.3.2...

$ irb
>> require 'rubygems'
=> false
>> require 'twitter4r'
LoadError: no such file to load -- twitter4r
       from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'
       from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in
`require'
       from (irb):2

Я скачалприложение http://files.rubyforge.vm.bytemark.co.uk/twitter4r/twitter4rails.post-0_2_4.zip, и оно работает только с twitter4r-0.2.4, а НЕ с последней версией twitter4r-0.3.2:

Последнее, в /config/environment.rb Iнужно указать:

RAILS_GEM_VERSION = '1.2.3' unless defined? RAILS_GEM_VERSION  

если я использую свою последнюю версию рельсов:

RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION 

Я получаю эту ошибку:

И это все :-)

Спасибо!

Запутанно имя драгоценного камня и имя требуют разные.В irb правильно работает:

require 'twitter'
