当我打开我的网页，我收到上述错误连同错误编译CSS资产
Started GET "/assets/application.css" for 127.0.0.1 at 2012-03-05 10:07:42 +0530
Error compiling asset application.css:
NoMethodError: undefined method `[]' for nil:NilClass
(in /Users/ritvvijparrikh/Projects/tr/app/assets/stylesheets/tr/sprites.css.scss)
Served asset /application.css - 500 Internal Server Error
我的文件sprites.css.scss没有改变长时间。但后来我最近升级到Rails 3.2.2
我sprites.css.scss文件

升级到Rails 3.2.2后，我遇到了类似的问题，但我不确定是因为这个还是完全不同的。奇怪的是'cap staging deploy'可以工作，但'cap production deploy'不能。 – thekingoftruth 2012-03-20 19:13:20
我在这里也遇到同样的问题。我发现注释掉使用'asset-url'助手修复错误的行（但显然破坏了你的样式表），所以我认为它与这个助手如何查找资产文件有关。 – SubmittedDenied 2012-05-10 20:28:28
