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。测试在我同事的机器上运行得很好。

我们正在使用 RVM + ruby​​ 1.8.7 + gemsets + bundler。Gems 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：

我的机器是 2011 款 MacBook Pro i7 四核，带有雪豹、自制软件、rvm、ruby、rvm infp 说：

打开 jruby-jar 的包装显示：drb 已包含在内。手动要求工作。但我无法弄清楚，问题是什么。通过进一步调查，我能够弄清楚实际的 java 命令行是什么，它应该启动 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")'

错误保持不变：
