Rails + Twitter Bootstrap: File to import not found or unreadable: twitter/bootstrap

Question

I am trying to set up Rails app with Twitter Bootstrap (the gem twitter-bootstrap-rails), but I still cannot get over the error

File to import not found or unreadable: twitter/bootstrap.

I found this issue on official Github of the gem, but none of solution from there have worked for me. Here's my setup: Gemfile

gem "twitter-bootstrap-rails"
gem 'font-awesome-rails'
gem 'sass-rails',   '~> 3.2.3'
group :assets do
  #gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'therubyracer', :platforms => :ruby
  gem 'uglifier', '>= 1.0.3'
end

application.css

 *= require_self
 *= require bootstrap_and_overrides
 *= require font-awesome
 *= require_tree .

bootstrap_and_overrides.css.sass

@import "twitter/bootstrap";
@import "twitter/bootstrap/bootstrap";
@import "twitter/bootstrap/responsive";

// Font Awesome
@import "fontawesome";

// Glyphicons
@import "twitter/bootstrap/sprites.scss";

What am I missing for correct set up?

Thanks

we had the same problem, i just restarted the rails server and it worked

If you already attempted to shut down the server and restart it, then your problem may be the cached css file that is generated from your sass file. The reason for this may be some varient of live reload which pre-renders several of the scss/haml type files. If that isn't the case then

1. Read the error message and determine the scss file that is causing the error.
2. Locate the css file that is generated along the sass file, (i.e. custom.css.scss would generate custom.css).
3. Delete that file, refresh the page and if this files delete the entire cache found under assets/stylesheets and temp/cache)

Answer 3

For some reason I had to explicitly require the gem to get it working. As suggested in this github issue comment to fix a similar error with bootstrap-sass, it's likely the gem is not loaded automatically. Add require "twitter-bootstrap-rails to e.g config/application.rb file to explicitly require it.
