生成Ruby on Rails支架时出错

Question

我是Ruby on Rails的新手，我正在尝试阅读有关如何生成基本Rails应用程序的初学者教程。 尝试生成支架时，出现以下错误：

C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-3.1.1/lib/rails/engine.rb：466：在routes': no >such file to load -- action_dispatch/routing/route_set (LoadError) from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties-3.1.1/lib/rails/engine.rb:519:in >来自C：/ Ruby192 / lib / ruby / gems / 1.9.1 / gems / railties-> 3.1.1 / lib / rails / initializable.rb：30：in instance_exec' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/initializable.rb:30:in运行中从C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-> 3.1.1 / lib / rails / initializable.rb ：55：在block in run_initializers' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/initializable.rb:54:in中的block in run_initializers' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/initializable.rb:54:in C：/ Ruby192 / lib / ruby​​ / gems / 1.9.1 / gems / railties-> 3.1.1 / lib / rails / initializable.rb：54：在run_initializers' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/application.rb:96:in初始化中！ 来自C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-> 3.1.1 / lib / rails / railtie / configurable.rb：30：in method_missing' from C:/Users/Spi/Documents/Komodo Projects/movielib/config/environment.rb:5:in > 'from C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-> 3.1.1 / lib / rails / application.rb：83 ：in require' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/application.rb:83:in require_environment中！ 从C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-3.1.1/lib/rails/commands.rb：22：in> <top (required)>' from script/rails:6:in require'from script / rails：6：in`'

我在运行Windows 7 64位的PC上安装了Ruby 1.9.2和Rails 3.1.1版本。 我正在运行的命令如下：

rails generate scaffold Scaff_test string:title

我在先前创建的Rails应用程序目录中时，从命令提示符运行此命令。 任何帮助将不胜感激！

该错误与路由有关。 作为生成所需文件的一部分，它将尝试更新routes.rb（位于config / routes.rb下）。

请检查文件是否存在，如果存在，请检查routes.rb的文件许可权
