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

@import "引导";

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

在我的 production.rb 中，我有：

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 assets:precompile，那有什么问题？

标签： ruby-on-rails ruby heroku deployment sass

【解决方案1】：

确保您在 Gemfile 中使用 bootstrap-sass gem

gem 'bootstrap-sass'

编辑：同样根据此处的另一个线程，显然包含连字符的文件可能存在问题。尝试删除连字符。

【讨论】：

这会产生不同的错误（例如“找不到要导入的文件”并给出它尝试过的搜索路径列表）。

【解决方案2】：

Sass 会寻找正确的语法，如果有任何“空白”，请检查您的 css 文件是否删除它

【解决方案3】：

您是否尝试过降级您的 sass gem？

试试这个：

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