蓝图CSS Rails 3.1帮助

Question

我的蓝图CSS在本地机器上工作，但是当我推到Heroku时，我会遇到一个错误。

我已经存储在我的 app/assets/stylesheets folder 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不预编译，我认为这可能是错误，但我不知道该如何解决。

这是我的Heroku日志：

Answer 1

我只是遇到了同样的问题。我通过设置解决了 config.assets.compile = true 在 config/environments/production.rb

编辑：在开发过程中，这可以正常工作，但是由于在运行时执行汇编而受到性能罚款。有关更好的解决方案，请参见下面的答案

Answer 2

解决此问题的一种方法是通过运行来预编译资产 rake assets:precompile. 。您必须通过添加来包括一个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

尝试设置您的：

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

在 config/environments/production.rb

我敢肯定，拥有比我更多的经验的人能告诉我们为什么所有CSS文件都没有预先编译为标准。我也只是刚开始！

至少有一个讨论：Rails 3.1资产管道 - 丢失公共/资产的文件 - 为什么这不是默认值？

Answer 4

我试图运行Rake Assets：预编译，无法正常工作。我在我的gemfile中有资产组。我在某个地方阅读了我应该确保预先编译生产环境的地方：

RAILS_ENV=production bundle exec rake assets:precompile

那也无济于事。我最终做了config.assets.compile = true，它运行良好，但我很想获得真正的解决方案。

我从来没有得到 -----> Preparing Rails asset pipeline 当他们推到Heroku时，他们说应该得到。
