Question

我对RoR很新，我正在尝试在heroku上部署应用程序。我正在尝试rake assets:precompile，但每次都失败：

rake aborted!
Sprockets::FileNotFound: couldn't find file 'bootstrap'
  (in C:/Users/%User%/Documents/GitHub/appname/app/assets/stylesheets/application.css:13)

Tasks: TOP => assets:precompile

这在本地和heroku服务器上都会发生。我的application.css看起来如下：

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.
 *
 *= require bootstrap
 *= require_tree .
 *= require_self
 */

我的Gem文件如下：

    source 'https://rubygems.org'
ruby '2.1.5'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.4'

group :development, :test do
  gem 'sqlite3'
end

group :production do
  gem 'pg'
end

gem 'chronic'
gem 'icalendar', '~> 2.1.1'

gem 'rails_admin'

gem 'tzinfo-data'

gem 'rails_12factor'

当我包含bootstrap-sass宝石时，是否有人知道为什么它会抛出错误，说它无法找到引导程序。

为什么我得到Sprockets :: FileNotFound
