bootstrap：要导入的文件未找到或不可读

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.

  source 'https://rubygems.org'
  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 'bootstrap-sass', '2.0.4'
  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

add your bootstrap-sass gem into the assets block
