ruby​​gem Twitter4R问题

Question

我想上手twitter4r但我有一些问题：

为什么我不能加载IRB宝石？

 
$ 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 

我已经下载了http://files.rubyforge.vm.bytemark.co.uk/twitter4r/twitter4rails.post-0_2_4.zip 应用程序，它仅适用于twitter4r-0.2.4，而不是与过去的版本 twitter4r-0.3.2：

     from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in 
`require' 
     from script/server:3 

最后一件事，在/到config/environment.rb我需要指定：

   RAILS_GEM_VERSION = '1.2.3' unless defined? RAILS_GEM_VERSION

，如果我用我最后的轨道版本：

  RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION

我得到这个错误：

而这一切:-)

谢谢！

混淆的宝石名称和要求名称是不同的。以下irb正常工作：

require 'twitter'
