我希望能够在rails中处理excel spreadhseets。
所以我正在使用spreadsheet库。
但是，当我使用红宝石安装电子表格时，我得到一个异常：

然后在我的doSomethingController中，我编写了代码：
require 'spreadsheet'
但服务器返回错误
cannot load such file -- spreadsheet
你能帮我弄清楚发生了什么以及如何解决异常吗
我的环境：
ruby 1.9.3
rubygem 1.8.16
检查你的宝石：
gem list
检查正在安装的那个：
gem list | grep spreadsheet
按照 http://rubygems.org/gems/spreadsheet 中的使用说明进行操作，其中还讨论了开发依赖项：
hoe ~> 2.13
rdoc ~> 3.10
有一个很棒的"入门"指南 http://spreadsheet.rubyforge.org/files/GUIDE_txt.html
维基 - http://spreadsheet.ch/也很有用。
