【问题描述】：
我正在尝试以生产模式在本地运行：
$ RAILS_ENV=production rails s
但我明白了：
/home/durrantm/.rvm/gems/ruby-1.9.3-p194@linker/gems/activesupport-3.1.8/li
b/active_support/dependencies.rb:306:in `rescue in depend_on': No such file
to load -- /home/durrantm/Dropnot/webs/rails_apps/linker/app/assets/../con
fig/environment (LoadError)
我可以创建一个全新的rails 3.1.8 应用程序并执行RAILS_ENV=production rails server，但我没有遇到这个问题。
我也可以 rails s 并且在开发模式下运行服务器正常而不会出错。
我也可以 RAILS_ENV=development rails s 并且在开发模式下运行服务器正常而不会出错。
fwiw，我的应用程序最初是一个 rails 2.3 应用程序，所以也许我遗漏了在 rails 中添加或更改的内容？
我确实有带有environment.rb 文件的config 目录。也许它被引用的方式是错误的？
我在config/application.rb 中添加了config.assets.enabled = true，但它没有帮助（没想到它是资产编译，但这是我发现的不同之处！）。

【问题讨论】：
-
有些奇怪。它正在寻找
app/目录中的config/目录。它不应该在那里看。 -
是的，这肯定是奇怪的部分......
-
是什么原因造成的？这是一个我已经运行了几年的应用程序，并通过几个 Rails 版本进行了升级，并且没有遇到过这样的问题。我目前正在通过
config/目录（现在我正在通过initializers/但还没有看到任何东西...... -
您是否正在尝试从 2 升级到 3？或者你有它在 3 上工作吗？
-
我让它在 Rails 3.1.8 上工作，但没有资产编译。我现在正试图让它与资产编译一起工作。该应用程序本身最初是在 Rails 2.3.8 左右开始的。
