不能生成腳手架

Question

我嘗試使用this tutorial，但腳手架生成代碼有一些問題。

application.rb中

從 this topic

Bundler.require(:default, Rails.env) if defined?(Bundler) 
#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 

採取的解決方案，但並不好這個問題。

Answer 1

這件事情與資產。我認爲你至少需要將你的rails升級到3.1。 3.2.3更好。

嘗試使用最新版本的rails 3.2.3創建新項目。

或試用此解決方案http://railscasts.com/episodes/282-upgrading-to-rails-3-1或教程書的最後一章http://russian.railstutorial.org/chapters/rails-3-1#top。

還有一個解決方案沒有升級，但我不確定。在您的config/application.rb中，嘗試找到config.assets.enabled並將其設置爲false。

Answer 2

Rails資產管道在Rails 3.1及更高版本之前不可用。我在C：/Users/Evgeny/Rails_projects/demo_app/config/application.rb的第55行猜測，你有一個config.assets行導致了這個問題。刪除該行或升級到Rails 3.1或3.2
