我正在将应用程序从 Rails 3.0.3 升级到 3.2.8。试图让资产进行预编译。我得到这个输出：

$ bundle exec rake assets:precompile
/usr/local/rvm/rubies/ruby-1.9.2-p320/bin/ruby /usr/local/rvm/gems/ruby-1.9.2-p320@pier-admin-32/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
rake aborted!
no such file to load -- sass/rails/compressor
  (in /home/danb/Documents/Projects/pier-admin/pier-admin/app/assets/stylesheets/application.css)

Tasks: TOP => assets:precompile:primary
(See full trace by running task with --trace)
rake aborted!
Command failed with status (1): [/usr/local/rvm/rubies/ruby-1.9.2-p320/bin/...]

Tasks: TOP => assets:precompile
(See full trace by running task with --trace)

对此我比较陌生，我不知道问题是什么。我之前没有使用资产，并且在升级过程中我尽量做到了最低限度。该应用程序在开发中工作。任何帮助，将不胜感激。

资产组是：

group :assets do
  gem 'sass'
  gem 'coffee-script'
  gem 'uglifier'
end

application.css 只有

/*
 * This is a manifest file that'll automatically include all the stylesheets available in this directory
 * and any sub-directories. You're free to add application-wide styles to this file and they'll appear at
 * the top of the compiled file, but it's generally better to create a new file per style scope.
 *= require_self
 *= require_tree . 
*/

:assets 组不会安装在生产环境中，因此您可能缺少这些 gem，并且 rake 失败。

一种选择是在开发中预编译，在 /public 中提交文件并将它们推送到生产服务器。

另一种是延迟初始化 application.rb 中的资产，例如：

if defined?(Bundler)
  # If you precompile assets before deploying to production, use this line
  # Bundler.require(*Rails.groups(:assets => %w(development test)))
  # If you want your assets lazily compiled in production, use this line
  Bundler.require(:default, :assets, Rails.env)
end
