rails 4: cannot load such file -- sass
ruby-on-rails, sass, twitter-bootstrap
Solution
Did you make sure that you also removed the sprockets `//= require` directive in your `application.css.scss` file?
Also, make sure all your gem versions are aligned. According to this rubygems page, version 2.3.2 of `boostrap-rails` requires version 3.1 for the `saas` gem. Running `bundle install` should also notify you of any gem version mismatches in your `Gemfile`.
Finally, if you're using Rails 4, why are you using an older version of `bootstrap-rails`? The latest stable version of `bootstrap-rails` is 3.1.1.0 (as of Feb 13, 2014).
Problem
I want to use bootstrap in my project. My operating system is Windows, Ruby version is 1.9.3, Rails version 4.0.4. I try to bundle one gem every time because there is dependence in some gem when I execute bundle install. ``` bootstrap-sass (2.3.2.0) sass (3.3.5, 3.2.19) sass-rails (4.0.2) sprockets (2.12.0, 2.11.0) ``` Now, I add `//= require bootstrap` into `application.js` and add `@import "bootstrap"` into `application.css.scss`. But when I start server, I got `Load Error in *Controller#home`: ``` cannot load such file -- sass (in D:/first_app/app/assets/style sheets / application.css.scss ``` Extracted source (around line #5): `<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %> <%= javascript_include_tag "application", "data-turbolinks-track" => true %> <%= csrf_meta_tags %>` ``` Rails.root: D:/rails_projects/first_app ``` Any advice?
