File to import not found in Rails 4

[Don Pinkus]

I'm trying to use the modular scale gem with Rails 4. However, after adding @import 'modular-scale'; I get the error File to import not found or unreadable: modular-scale.

1. Add gem "modular-scale" to gemfile.rb
2. Run $ bundle install. Make sure gem is installed.
3. Add @import 'modular-scale'; to application.css.scss

Are there other steps that need to happen when setting it up on Rails?

Are you using Compass with Rails 4? require 'modular-scale' should be added to your Compass config. If you are not using Compass I recommend using vanilla Sass install method: https://github.com/modularscale/modularscale-sass#vanilla-sass
