为什么rake资产:precompile产生一个空的css样式表?

我正在使用 sass-rails haml-rails 这些宝石,因此我可以用HAML-sass样式编写css文件。

问题是,当我想要进行生产并预编译我的样式表时,命令rake assets:precompile运行时没有错误,但生成的application.css为空。

这是我的Gemfile:

source 'https://rubygems.org'

gem 'rails', '~>3.2'
gem 'pg', '>= 0.14'
gem 'haml-rails' #, '~> 0.3'

group :development, :test do
  gem 'factory_girl_rails'
end

group :developpement do
  gem 'rspec-rails', '>= 2.11'
  gem 'capistrano', '>= 2.12'
  gem 'faker', '>= 1.0'
  gem 'rvm-capistrano'
end

group :test do
  gem 'rspec', '>= 2.11'
  gem 'webrat', '>= 0.7'
  gem 'spork-rails', '>= 3.2'
end

group :assets do
  gem 'sass-rails',   '>= 3.2.3'
  gem 'coffee-rails', '>= 3.2.1'
  gem 'compass-rails', '>= 1.0'
  gem 'execjs'
  gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'
gem 'annotate'
gem 'excel_rails' #, '~> 0.3'
gem 'spreadsheet' #, '~> 0.7'
gem "schema_plus", :git => "git://github.com/lomba/schema_plus.git"
gem 'ar-octopus' #, '~> 0.3'
gem 'squeel' #, '~> 1.0'
gem 'devise' #, '~> 2.1'
gem 'role_model'
gem 'declarative_authorization'
gem 'rails-translate-routes'  #, '~> 0.1'
gem 'validates_timeliness'  #, '~> 3.0'

这是我的(空)app / assets / stylesheets / application.css.sass

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 */

我根据https://github.com/rails/sass-rails上的建议删除了以下注释行:

 *= require_self
 *= require_tree .

我的css.sass文件存储在这里:

  • 应用程序/资产/样式表/ screen.css.sass
  • app / assets / stylesheets / partials /(screen.css.sass引用的许多部分文件_ *。css.sass)

=== UPDATE ===

请注意我正在使用COMPASS gem。因此,mixin和变量需要在样式表之间共享。

以防万一,这是我的app / assets / stylsheets / screen.css.sass文件:

// This import applies a global reset to any page that imports this stylesheet.
@import blueprint/reset

// To configure blueprint, edit the partials/base.sass file.
@import partials/base

@import blueprint/interaction
@import blueprint/typography
@import blueprint/grid
@import blueprint/buttons
@import blueprint/utilities

@import compass/layout/grid-background
@import compass/typography/lists/inline-block-list
@import compass/typography/lists/horizontal-list
@import compass/utilities/general/float
@import compass/css3/border-radius
@import compass/css3/box-shadow
@import compass/css3/text-shadow
@import compass/css3/transition

@import partials/opf_mixins_et_functions
@import partials/link_icons
@import partials/typo
@import partials/application
@import partials/affichage_donnees
@import partials/tableau_edition
@import partials/page
@import partials/form
@import partials/feedback

===更新2 ===

我意识到我的Gemfile会让我在制作中遇到麻烦,因为我将以下宝石放在资产组中:

group :assets do
  ...
  gem 'execjs'
  gem 'therubyracer', :platforms => :ruby
  ...
end

因为生产环境也需要一个javascript解释器...... 所以我会将它们移到我的Gemfile中的任何组之外。

欢迎任何建议

建议您删除这两行,但仍需要自己包含文件:

*= require screen
*= require_dir partials/

请注意:但是这不像@import那样 - 你不会让你的mixins和变量共享。使用真实的@import

好的我用以下解决方案解决了它:

遵循最后一个答案的精神,似乎在我的/app/assets/styelsheets/application.css.sass的末尾添加以下行解决了我的问题:

@import screen

screen.css.sass的每个引用的部分样式表将被自动导入。

答案 2 :(得分:0)

我的预编译资产(application.js和application.css)是空的......

是什么解决了我的问题:

  • 在Gemfile中设置最后一个rails版本(现在为3.2.14)

  • bundle update

  • bundle install

  • 重新启动应用touch tmp/restart.txt
