我正在尝试将 Redcloth 添加到我的 Gem 文件中，当我运行“捆绑安装”时，我得到以下信息：
使用本机扩展安装 RedCloth (4.2.6) /home/user/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:529:in `rescue in阻止 build_extensions'：错误：无法构建 gem 原生扩展。(Gem::Installer::ExtensionBuildError)
/home/user/.rvm/rubies/ruby-1.9.2-p136/bin/ruby extconf.rb
Gem 文件将继续安装在 /home/user/.rvm/gems/ruby-1.9.2-p136@vendorguide/gems/RedCloth-4.2.6 以供检查。
结果记录到 /home/user/.rvm/gems/ruby-1.9.2-p136@vendorguide/gems/RedCloth-4.2.6/ext/redcloth_scan/gem_make.out

如果我运行“gem install RedCloth”然后运行“bundle install”，它可以工作，但是当我实际尝试在模型“Vendor.rb”中使用 RedCloth 时，我得到：
未初始化的常量 Vendor::RedCloth
这是我的宝石文件：
宝石'导轨'，'3.0.3' 宝石“指南针”，“>= 0.10.6” 宝石“哈姆” 宝石'formtastic' gem '设计', :git => 'git://github.com/plataformatec/devise.git', :branch => 'master' gem 'oa-oauth', :require => "omniauth/oauth" 宝石“莫格利” 宝石“达利” 宝石'特殊' 宝石'json' 宝石'红布' 组 :test, :development 做 宝石“红宝石调试19” gem "rspec-rails", "~> 2.4" gem 'sqlite3-ruby', :require => 'sqlite3' 宝石“杏” 宝石'ruby_parser' 宝石'heroku' 宝石“长笛” 结尾 组：测试做 宝石'黄瓜导轨' 宝石“水豚” 宝石'database_cleaner' 宝石“摩卡” 宝石'factory_girl_rails' 宝石“应该” 宝石'ZenTest' 宝石“假网” 结尾
这是我的模型：
