我最近将我的应用程序从 Rails 2.1.2 版升级到 2.2.2 版。它在开发和我的登台系统上进行了测试。当我转向生产时，它无法通过 environment.rb 文件一直加载。（为什么，哦，为什么，它总是在生产中！？！）
下面是我的 environment.rb 文件

如果我将 rails gem 设置为用于 2.1.2 版本，则所有内容都会加载并且所有puts语句都按预期打印。当我将 gem 版本更改为 2.2.2 时，我看到的最后一条语句是“ setting smtp settings”。
当我将该Rails::Initializer do |config|部分移至底部时，它的失败方式比现在更糟。
系统上加载的 ruby 版本是 Ruby 1.8.6 patchlevel 111。它在 RHEL5-64bit 上运行。
我难住了。想法？建议？
