bootstrap :File to import not found or unreadable - ruby-on-rails

Question

I have found already some topics about my problem but I didnt understand how it should be fixed.
I was following http://ruby.railstutorial.org/chapters/filling-in-the-layout#fnref-5_5 tutorial and stuck by importing the bootstrap in app/assets/stylesheets/custom.css.scss.
That is my Gemfile:
source 'https://rubygems.org'
gem 'bootstrap-sass', '2.0.4'
gem 'rails', '3.2.8'
group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.11.0'
end
Gems used only for assets and not required
in production environments by default.
group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.2'
group :test do
gem 'capybara', '1.1.2'
end
group :production do
gem 'pg', '0.12.2'
end
And what error I get on localhost/sample_app/home
Sass::SyntaxError in Static_pages#home
Showing c:/Users/katja/Arbeit/rails_projects/sample_app/app/views/layouts/application.html.erb where line #5 raised:

I am using Windows and GitBash. I ahve already tried to delete tmp/cache, it didnt help.
Everything runs perfect but when I add #import "bootstrap"; to a cusom.css.scss, I get an error.

add your bootstrap-sass gem into the assets block
