Sprockets::FileNotFound couldn't find file 'bootstrap' with type 'text/css' <p>So this is the error I am getting in my browser when I try to run the rails server:</p> <pre><code> [couldn't find file 'bootstrap' with type 'text/css'] </code></pre> <p>I have this in my gemfile:</p> <pre><code> gem 'bootstrap-sass', '~&gt; 3.3.5.1' </code></pre> <p>And this is my application.css.scss file: </p> <pre><code> *= require bootstrap *= require_tree . *= require_self */ @import "bootstrap"; </code></pre> <p>Does anyone know how to get this up and running?? </p>
