CSS没有在Heroku中加载

我将我的应用程序部署到Heroku,但只加载了资产\图像。 CSS文件(特别是包含90%CSS的文件,custom.css)未加载。 我在本地预编译资产并将它们推送到Heroku而没有运气。 仅加载图像,而不是custom.css文件。

我注意到Heroku日志中有一个有趣的错误:

开始获取“/users/css/parallax-slider.css”为77.777.777.77于2013-06-13 02:42:09 +0000 2013-06-13T02:42:09.016864 + 00:00 app [web.1] :ActionController :: RoutingError(没有路由匹配[GET]“/users/css/parallax-slider.css”):

为什么在我的用户控制器文件夹中查找css? 这是应用程序无法加载custom.css文件的原因吗?

任何帮助将不胜感激。 我在这上面度过了两个不眠之夜,我完全被难过了。

请在您的production.rb中config.serve_static_assets = true进行此更改

请让我知道发生了什么。它会起作用..

谢谢

使用更新您的gemfile

  *group :production, :staging do gem 'rails_12factor' end* 

安装捆绑包并将其推送到heroku

  Installing rails_serve_static_assets (0.0.1) Installing rails_stdout_logging (0.0.1) Installing rails_12factor (0.0.2) 

当我遇到同样的问题时,它会帮助我。

如何改变application.css(.scss)(比如添加新的空行)并提交它? 似乎Heroku正在检查diff文件并相应地预编译资产。 我碰巧意外地知道它,所以你可以试试它是否有帮助。
