我处在一个不可行的情况，我必须在ubuntu服务器上部署一个ruby one rail应用程序，没有任何文档，也没有ruby（或ruby on rails）的经验。
我尝试按照各种论坛/教程中列出的步骤进行操作。我已经在端口80上启动了WEBricks服务器，但是当我尝试从浏览器访问Web应用程序时，我得到以下内容而不是浏览器。
couldn't find file './compiled/admin' under '/home/ubuntu/www/my-app/app/assets/stylesheets' with type 'text/css'
然后有人建议我跑
rake assets:precompile
当我运行此命令时，出现以下错误...
DEPRECATION WARNING: Currently, Active Record suppresses errors raised within `after_rollback`/`after_commit` callbacks and only print them to the logs. In the next version, these errors will no longer be suppressed. Instead, the errors will propagate normally just like in other Active Record callbacks.
You can opt into the new behavior and remove this warning by setting:
config.active_record.raise_in_transactional_callbacks = true

答案 0 :(得分：1)
您的问题是您需要生成将放在此stylesheets/compiled文件夹中的文件。
两个选项：
了解如何生成它们（如果您有关于bower，grunt等的文件，请查看项目的根目录。如果您这样做，我需要启动它们以实际生成文件并在资产编译之前添加相应的部署规则或提交结果。
从admin.css文件中删除此行：
*= require ./compiled/admin
