爲什麼逃課的Heroku對Rails 3.1的應用程序預編譯步驟？

我瞎搞與導軌3.1應用程序，並部署到Heroku的雪松。爲什麼逃課的Heroku對Rails 3.1的應用程序預編譯步驟？

當按下一個應用程序，Heroku的跳過預編譯的步驟，無需拋出一個錯誤：

Your bundle is complete! It was installed into ./vendor/bundle 
Cleaning up the bundler cache. 
-----> Writing config/database.yml to read from DATABASE_URL 
-----> Rails plugin injection 
     Injecting rails_log_stdout 
     Injecting rails3_serve_static_assets 
-----> Discovering process types 
     Procfile declares types  -> (none) 
     Default types for Ruby/Rails -> console, rake, web, worker 
-----> Compiled slug size is 16.2MB 
-----> Launching... done, v35

我最後一次被推到Heroku的（也許一個月前），它有沒有問題預編譯的資產。

gem 'rails', '3.1.1.rc2', :git => 'git://github.com/rails/rails.git', :branch => '3-1-stable'

UPDATE：

我能得到的Heroku通過從application.rb中以下預編譯：

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

，並替換：

# If you have a Gemfile, require the gems listed there, including any gems 
# you've limited to :test, :development, or :production. 
Bundler.require *Rails.groups(:assets) if defined?(Bundler)

這似乎爲我工作。推向heroku仍然說有錯誤，但頁面加載正確。 –
