大家好。

我的 Rails 要在本机试试看上 production 环境，上之前我要 rake assets:precompile ，

但它只编译 application.css ，其它目录底下的 *.scss.css 都不会编译。

有人知道该怎么解决吗？

目前里面只有一个 css + scss：

└── stylesheets
    ├── application.css
    └── projects.css.scss

我试过：

• 把 projects.css.scss 拿掉就 OK 了，但是我需要 scss ... ==> NO
  
• 改 config/enviroment/production.rb 里的 config.assets.compile = true ==> OK!
  
• bundle exec rake assets:precompile ==> 同样的错误
  
• 重装 gem -> 还是不行

环境 Gemfile.lock：
