rubygem Twitter4R问题
我试图开始使用twitter4r，但我遇到了一些问题：
为什么我不能在IRB中加载宝石？
$ sudo gem install twitter4r
Successfully installed twitter4r-0.3.2
1 gem installed

$ irb

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，不适用于最新版本twitter4r-0.3。 2：

最后一件事，在/config/environment.rb我需要指定：
RAILS_GEM_VERSION = '1.2.3' unless defined? RAILS_GEM_VERSION
如果我使用我最后的rails版本：
RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION
我得到这个错误：

就这样 ：-）
谢谢！
混淆的宝石名称和要求名称是不同的。 以下在irb中正常工作：
require 'twitter'
