The bootstrap-sass-rails gem is deprecated starting with version 22.214.171.124. There is an official Sass port of Bootstrap now which can be found within the twbs organization on GitHub:

Remove the twitter/ prefix from all your
= require statements:
@import "twitter/bootstrap"; @import "twitter/bootstrap/modal";
@import "bootstrap"; @import "bootstrap/modal";
//= require "twitter/bootstrap"; //= require "twitter/bootstrap/modal";
//= require "bootstrap"; //= require "bootstrap/modal";
Thank you for using bootstrap-sass-rails!
