Question

我最近被分配了一项任务来更改网站的主题。最初它是使用bootstrap，我使用bootswatch主题来重新设计它。一切都很好，在当地看起来很好。但是在我将资产部署到生产环境之前，我必须预先编译我的资产。

`$ bundle exec rake assets:precompile`

失败，出现以下错误。我花了几天时间在互联网上挖掘，但对Avail没有帮助。

使用jruby-1.7.18

Gemfile的一部分

# Styling
gem 'sass-rails',   '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'uglifier', '>= 1.0.3'
gem 'jquery-ui-rails'
gem 'jquery-rails', '~> 2.3.0'
gem 'bootstrap-datetimepicker-rails'
gem 'jquery_datepicker'
gem 'bootstrap-sass'
gem 'twitter-bootstrap-rails'
gem 'therubyrhino'
gem 'less-rails'

错误

Answer 1

应该有一个bootstrap-overrides或类似的样式表，你应该定义@ alert-padding变量

Rails资源预编译失败的未定义变量
