ruby-on-rails之蓝图 css rails 3.1 帮助

2024年12月31日14飞鱼

我的蓝图 css 可以在我的本地机器上运行,但是当我推送到 heroku 时出现错误。

我的 app/assets/stylesheets folder 中存储了蓝图这是我正在使用的样式表标签:

<%= stylesheet_link_tag    "application" %> 
<%= stylesheet_link_tag 'blueprint/screen', :media => 'screen' %> 
<%= stylesheet_link_tag 'blueprint/print',  :media => 'print' %> 

在我的 heroku 日志中,它说 application.css 未预编译,我认为这可能是错误,但我不知道如何修复它。

这是我的heroku日志:

请您参考如下方法:

我只是遇到了同样的问题。我通过设置 config.assets.compile = true 解决了它在 config/environments/production.rb
编辑:这在开发时工作正常,但在运行时执行编译时会降低性能。请参阅下面的答案以获得更好的解决方案
