我用黄瓜设置了一个rails 2.3项目，它工作正常。现在我想运行javascript测试，并使用Akephalos进行设置。现在有趣的事情。测试在我的同事机器上运行得很好。
我们正在使用RVM + ruby 1.8.7 + gemsets + bundler。宝石都已安装，但每当我在我的机器上启动特定功能时，如下所示：
bundle exec cucumber featues/myfeature.feature
它说：
LoadError: UNIXServer is required

打开jruby-jar的包装显示：包含了drb。手动要求工作。但我无法弄清楚，问题是什么。通过进一步的调查，我能够弄清楚，实际的java命令行是什么，应该带来akephalos服务器：
java -Xmx128M -cp /Users/christoph/.rvm/gems/ruby-1.8.7-p334@betterplace/gems/jruby-jars-1.6.0/lib/jruby-core-1.6.0.jar:/Users/christoph/.rvm/gems/ruby-1.8.7-p334@betterplace/gems/jruby-jars-1.6.0/lib/jruby-stdlib-1.6.0.jar org.jruby.Main -I vendor:/Users/christoph/.rvm/gems/ruby-1.8.7-p334@betterplace/gems/akephalos-0.2.4/lib:/Users/christoph/.rvm/gems/ruby-1.8.7-p334@betterplace/gems/akephalos-0.2.4/src -r akephalos/server -e 'Akephalos::Server.start!("/tmp/akephalos.1586.sock")'
