我使用gem bundler（v.0.9.6）和Rails 2.3.5，rubygems 1.3.6和ruby 1.8.7（在Snow上豹）。我的Gemfile看起来像这样：Selenium模式下的黄瓜和WebRat：使用gem包时无法启动mongrel_rails
source :rubyforge
source "http://gems.github.com"
gem "rails", "2.3.5"
gem "ruby-debug"

gem "nokogiri"
gem "state_machine"

end

gem 'fakeweb'
gem 'mongrel' #Selenium needs this
end
到目前为止好。我已经成功使用捆绑器几个星期了。然而，我开始在Selenium模式下使用Cucumber和WebRat来测试站点的一些ajaxy特性，并且每当我运行该功能时，WebRat都告诉我Rails服务器已启动，但我总是得到一个XHR_ERROR，Selenium不能找不到网址。 嗯，它发生了服务器没有启动。
于是，我打开webrat/lib中/ webrat /硒/ application_servers/rails.rb文件，并把一个调试器语句启动方法。再次运行功能，当调试器触发，我打印的START_COMMAND返回闪避，这是：
mongrel_rails start -d --chdir='/Users/fullofcaffeine/Projetos/myproject' --port=3001 --environment=test --pid /Users/fullofcaffeine/Projetos/myproject/tmp/pids/mongrel_selenium.pid
我复制并在控制台贴吧，删除从最终-d和&，这里的我得到的输出：

检查它试图加载从杂种的路径：“〜/ .bundle/...”，但杂种安装为系统的宝石。 Bundle处理系统宝石的加载在其他情况下罚款，但在这种特殊情况下，我不知道为什么它是失败:(。
我试着再次运行“捆绑安装”，它总是说：
从系统安装杂种（1.1.5） 宝石
我试图从系统中卸载杂种来尽量让捆在〜/ .bundle安装（因为这似乎是错误的来源，因为杂种是在这条路上搜索ing我开始像上面的mongrel_rails），但我无法做到这一点。
gem uninstall mongrel
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d mongrel`
当我运行 “宝石名单| grep的杂种”，我得到：
mongrel (1.1.5)
奇怪。
我只是希望能够在使用gem bundler的同时成功运行Cucumber和WebRat + Selenium，但是这使我疯狂。
任何人都可以启发我吗？
你能否确认这个变通方法是否加载所有从包钢轨的宝石？或者做杂种和所有积极的*宝石结束从系统gemenv加载？ – tribalvibes 2010-10-07 00:10:51
