“没有这样的文件加载 - redis”异常

Question

我安装了redis-2.2.2。但是在需要时我得到了例外：

/Library/Ruby/Site/1.8/rubygems/custom_require.rb:36:in `gem_original_require': no such file to load -- redis (LoadError)
from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:36:in `require'
from methods.rb:2

代码：

require 'rubygems'
require 'redis'

宝石清单如下：

activesupport (2.3.5, 2.2.3, 1.4.4)
capistrano (2.5.2)
cgi_multipart_eof_fix (2.5.0)
daemons (1.0.10)
