Question

我正在编写一个ruby应用程序，当我启动程序时它需要一堆宝石。例如：

require "active_record"
require "RedCloth"
require "rchardet"
require "mailfactory"
require "net/smtp"

但是，当我使用sudo gem install rails --version=2.1.1安装rails并尝试将rails添加到列表中时，将require "rails"置于顶部，如下所示：

require "rails"
require "active_record"
require "RedCloth"
require "rchardet"
require "mailfactory"
require "net/smtp"

我的应用程序打破了这一行：/usr/local/lib/site_ruby/1.8/rubygems/core_ext/kernel_require.rb:51：in`gem_original_require'：没有这样的文件要加载 - rails（LoadError）

当我执行gem list Rails时：

    emai@myserver:/usr/local/www/sl-exchange$ gem list

那里有铁轨！有谁知道发生了什么事？

Rubygems：即使安装了Rails，也没有这样的文件来加载 - rails（LoadError）
