我使用Boostrap。在 app / assets / stylesheets.css.scss 中，我有：

@import＆＃34; bootstrap＆＃34;;

和 vendor / assets / stylesheets 我有bootstrap.css和bootstrap.min.css

在我的 production.rb 中，其中包括：

config.serve_static_assets = true
config.assets.compile = true
config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
config.cache_store = :dalli_store
config.assets.precompile += %w( bootstrap/*.css bootstrap/*.js )

我显然使用rake资产：预编译，那么它有什么问题？

Answer 1

确保您在Gemfile中使用bootstrap-sass gem

gem 'bootstrap-sass'

编辑：另外根据这里的另一个帖子，显然包含连字符的文件可能存在问题。尝试删除连字符。

Answer 2

你有没有尝试降级你的宝石？

试试这个：

gem "sass", "~> 3.2.5"
gem 'sass-rails'

Answer 3

Sass查找正确的语法请检查您的css文件，如果有任何“空格”删除它
