我正尝试在生产模式下本地运行：
$ 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应用并执行RAILS_ENV=production rails server，但我没有遇到此问题。
我也可以做rails s并且在开发模式下运行服务器没有错误。
我也可以做RAILS_ENV=development rails s并且在开发模式下运行服务器没有错误。
fwiw，我的应用程序最初是一个rails 2.3应用程序，所以也许我错过了在rails中添加或更改的内容？
我的config目录中包含environment.rb文件。也许它被引用的方式在某种程度上是错误的？
我将config.assets.enabled = true添加到config/application.rb但它没有帮助（没想到它是资产编译，但这是我发现的差异！）。

改变了一些事情。其中一个主要是在尝试在本地（仅）运行时在config/environments/production.rb中本地启用静态资产，并在推送到生产Web服务器之前将其恢复。我不知道。

好像你的旧assets目录住在其他地方（可能在public），现在它在app/assets，但它不知道它，有些文件试图加载environment.rb。只需仔细检查资产目录。
