如何在 rails 4 中为 Sass 启用源映射? [英] How can I enable Source Maps for Sass in rails 4?

问题描述

根据这个问题

您可以在此处找到存储库:https://github.com/sass/sassc-rails

According to this issue https://github.com/rails/sass-rails/pull/192
sass-rails hasn't support for Sass 3.3 yet.

But it seems that sass-rails-source-maps has been depending on Sass 3.3 since the very beginning. So is there a way to use this gem with sass-rails?

According to the readme with sass-rails-source-maps, Chrome dropped support of the Source Maps files from Sass older than version 3.3.

Does that mean there is no way of using Sass Source Maps with Chrome devtools now?

解决方案

There is a great new drop in replacement for sass-rails, which is not only faster, but also has the option to use inline source-maps.

Just add it to your Gemfile

#gem 'sass-rails', '~> 5.0'
gem 'sassc-rails'

and add the configuration

# config/environments/development.rb
config.sass.inline_source_maps = true

Don't forget to restart your server, then you should see it working in the inspector:
