Rails 4 + bootstrap set up assets

Question

I am trying to setup bootstrap on Rails4 using bootstrap-sass and I am getting this famous error:

Sprockets::FileNotFound - couldn         


        

Answer 1

Installing the Bootstrap Gem

1.) Add the Bootstrap Gem:

gem 'bootstrap-sass'

2.) Understand The Application.css File app/assets/stylesheets/application.css

Application.css takes all the other files in your /stylesheets directory and combines them for when you run your app.

3.) Create a New SCSS File (app/assets/stylesheets/bootstrap_and_customization.css.scss)

@import 'bootstrap';

4.) Require Bootstrap's JavaScript

...
//= require jquery
//= require jquery_ujs
//= require bootstrap <--
//= require turbolinks
//= require_tree .

5.) Rails Assets

group :production do
  gem 'rails_12factor'
end

6.) Bundle Install & Restart Server

Thats should be it !
