我正在尝试部署 Rails 应用程序，但遇到了资产预编译错误。根据生产日志，该错误是由名为 screen.css 的“蓝图”CSS 脚本引起的（如您在下面的错误输出中看到的）。然而，根据生产日志，该资产实际上确实是经过预编译的。我尝试将 screen.css 和 print.css 显式添加到预编译数组中，在 application.rb 和 config/environments/production.rb 文件中，如下所示
config.assets.precompile = %w(screen.css print.css)
但无济于事。我还尝试在本地预编译我的资产并将整个内容推送到服务器。我已经尝试过这里列出的所有建议：blueprint/screen.css 未预编译 https://stackoverflow.com/questions/7443536/blueprint-screen-css-isnt-precompiled和这里：蓝图 CSS Rails 3.1 帮助 https://stackoverflow.com/questions/7300532/blueprint-css-rails-3-1-help同样的问题在这里仍未解决：Ruby on Rails 3.2 编译资源无法正常工作 https://stackoverflow.com/questions/9105027/ruby-on-rails-3-2-compiled-assets-are-not-working
我不知道接下来要尝试什么来解决此错误。任何帮助将不胜感激！下面是日志输出以及我的部署文件、cap 文件和 application.rb 文件。预先感谢您提出的任何建议！
以下是部署后日志文件的一些输出，您可以在其中看到 screen.css 已预编译。错误输出如下：
