我似乎无法安装 Gitorious。我试图不安装 Ruby 企业版，但除此之外，我一直遵循 Ubunut 的说明（有一些错误，但我已经解决了这些错误）。我已经安装了许多缺少的包和 gem，但是现在当我尝试迁移数据库时我被卡住了。我收到以下错误：
耙中止！
nil:NilClass 的未定义方法“[]”
跟踪看起来像这样：

我的理解是我声称我缺少一些依赖项，但我检查了 /var/www/gitorious/config/environment.rb 中的依赖项是否已安装。
我还在 custom_require.rb 中放了一个打印来打印路径变量，最后一个打印是“active_support/dependencies”。
有谁知道问题是什么或我该如何进一步调试？我可以以某种方式打印确切的缺失依赖项吗？甚至可以在不安装整个 Ruby 企业版的情况下安装 gitorious 吗？
