ruby-on-rails - Rails - 使用 ruby​​gems 安装电子表格 gem 时出错

Question

我希望能够处理 Rails 中的 excel 电子表格。
所以我正在使用 spreadsheet图书馆。
但是，当我使用 ruby​​gems 安装电子表格时，出现异常:

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我如何修复异常

我的环境:

ruby 1.9.3
rubygem 1.8.16

Answer 1

检查您的 gem :

gem list

检查正在安装的那个:

gem list | grep spreadsheet 

按照 http://rubygems.org/gems/spreadsheet 上的使用说明进行操作它还谈到了开发依赖:

hoe ~> 2.13   
rdoc ~> 3.10  

在 http://spreadsheet.rubyforge.org/files/GUIDE_txt.html 上有一个很棒的“入门”指南。

维基 - http://spreadsheet.ch/也很有用。
