You're getting a ..:14 because Chrome is looking for the SASS files but is unable to, due to the lack of media query in the CSS file.
Here's a prefix example your css should output:
@media -sass-debug-info{filename{font-family:file\:\/\/\/Users\/kai\/Play\/live\/screen\.scss}line{font-family:\0000311}}
.box {
..
}
Hope this helps other understand why this occurs! :)
Do you have the 'sass-rails' gem in your Gemfile? It's possible to have the asset pipeline work with just the 'sass' gem, but to get the full debug-info that Chrome requires you need to be using 'sass-rails' and specify the config options mentioned in the post.
- You need to be using 'sass-rails', not 'sass', in your Gemfile for config.sass to work. Don't put it in the :assets group, either.
- You must set config.sass.compress = false (or rather, you must not set it to true!)
- You'll probably need to blow away your assets cache (tmp/cache/assets/* or public/assets/*) to see the changes.
I just got it working with a Rails app at work, and I am pleased with the results. Chrome Web Inspector continues to make my life easier!
