Ruby on Rails：在Ubuntu 9.0.4中安装gitorious的问题

Question

我似乎无法安装Gitorious。我试图不安装Ruby Enterprise Edition，但除此之外我一直在遵循Ubunut的说明（有一些错误，但我已经解决了这些问题）。我已经安装了许多丢失的软件包和宝石，但现在我在尝试迁移数据库时遇到困难。我收到以下错误：

rake aborted！

未定义的方法`[]'为nil：NilClass

Trace看起来像这样：

我的理解是我声称我缺少一些依赖，但我已经检查过/var/www/gitorious/config/environment.rb中的依赖项已经安装。

我还在custom_require.rb中打印一个打印路径变量，最后一个打印是“active_support / dependencies”。

有谁知道问题是什么或我如何进一步调试？我可以以某种方式打印确切的缺失依赖吗？是否可以在不安装整个Ruby Enterprise版本的情况下安装gitorious？

我从Gitorious讨论组询问了这个问题，原因是默认的gitorious.yml文件只有测试环境的设置。通过将这些设置复制到生产环境，我解决了这个问题。
