Ruby on rails 我的资产没有在Heroku上预编译

我的资产没有在Heroku上预编译。我在cedar上运行，并将application.js和application.css定义为（js）：

当我在我的机器上用

bundle exec rake assets:precompile RAILS_ENV=production

js和css l是有效的。当我部署时，我看到：

-----> Preparing app for Rails asset pipeline
   Running: rake assets:precompile
   DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released.

   Asset precompilation completed (6.04s)

我的production.rb如下所示：

//= require_tree .

  ...
