蓝图css rails 3.1帮助

我的蓝图css在我的本地机器上工作，但是当我推送到heroku时我得到一个错误。

我的蓝图存储在我的app/assets/stylesheets folder ，这里是我正在使用的样式表标签：

   'screen' %>  'print' %> 

在我的heroku日志中，它说application.css没有预编译，我认为这可能是错误，但我不知道如何解决它。

这是我的heroku日志：

Answer 1

我刚遇到同样的问题。 我通过在config/environments/production.rb设置config.assets.compile = true来解决它

编辑：这在开发时工作正常，但在运行时执行编译时性能下降。 请参阅下面的答案以获得更好的解决方案

Answer 2

解决此问题的一种方法是通过运行rake assets:precompile来预编译rake assets:precompile 。 你必须通过添加包含一个javascript运行时

 # Gems used only for assets and not required # in production environments by default. group :assets do gem 'therubyracer' gem 'sass-rails', " ~> 3.1.0" gem 'coffee-rails', "~> 3.1.0"a gem 'uglifier' end 

到Gemfile并运行bundle install 。

Answer 3

尝试设置你的：

 config.assets.precompile += %w( blueprint/screen.css blueprint/print.css ) 

在config/environments/production.rb

我确信有比我更多经验的人可以告诉我们为什么所有的css文件都没有作为标准预编译。 我也刚刚开始！

这里至少有一个讨论： Rails 3.1资产管道 – 从公共/资产中丢失文件 – 为什么这不是默认值？

Answer 4

我试图运行rake资产：预编译并且无法使其工作。 我的Gemfile中有资产组。 我在某处读到了我应该确保预编译生产环境：

RAILS_ENV=production bundle exec rake assets:precompile

这也没有帮助。 我最终做了config.assets.compile = true，这很好，但我希望得到真正的解决方案。

在推送到他们说应该得到的heroku时，我从来没有得到-----> Preparing Rails asset pipeline 。
