无法预编译资产Rails 4 bootstrap-sass DXImageTransform错误

Question

我试图预编译生产资产。除非我将引导程序和font-awesome资产作为静态文件（或来自CDN的主机）包含在内，否则当尝试编译生产资产时，sass-rails会失败。我的Gemfile看起来是这样的：

# Default asset gems 
gem 'coffee-rails', '~> 4.0.0' 
gem 'sass-rails' , '~> 4.0.3' 
gem 'uglifier' , '>= 1.3.0' 

# Default gems 
gem 'jbuilder', '~> 2.0' 
gem 'sdoc' , '~> 0.4.0', group: :doc 

# Added gems 
gem 'carrierwave' 
gem 'pg' 
gem 'turbolinks' 
gem 'restforce' 

# Asset gems 
gem 'jquery-rails' 
gem 'autoprefixer-rails' 
gem 'bootstrap-sass' 
gem 'font-awesome-sass' 
gem 'handlebars_assets' 
gem 'iconv' 

当我尝试编译资产，我收到以下错误：

➜ stylesheets git:(master) ✗ rake assets:precompile

/home/ubuntu/.rvm/gems/ruby-2.1.3/gems/sass-3.2.19/lib/sass/scss/parser.rb:529:in `ruleset' 

app.css文件：

* 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. 
* 
*= require jquery-ui 
*= require sweetalert 
*= require vendors 
*= require_tree . 
*/ 

我SCSS文件：

@import "font-awesome-sprockets"; 
@import "font-awesome"; 
@import "bootstrap-sprockets"; 
@import "bootstrap"; 

我看过这个问题repor特德在这里：https://github.com/rails/sass-rails/issues/37 但这个问题已经有几年了。

Answer 1

删除progid和DXImageTransform.Microsoft.gradient之间的空格。

为前，

旧语法

filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#7adddd', endColorstr='#39cccc', GradientType=0) !important;

新的语法

filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#7adddd', endColorstr='#39cccc', GradientType=0) !important;

您可以在新语法看到，我已删除多余的之间的空间progid和DXImageTransform.Microsoft.gradient()。
