生成Ruby on Rails脚手架时出错

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。在尝试生成脚手架时，我收到以下错误：

  

C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-3.1.1/lib/rails/engine.rb:466:in 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 > block 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 run'     来自C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-> 3.1.1 / lib / rails / initializable.rb:55:in block in run_initializers' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/initializable.rb:54:in each'     来自C：/Ruby192/lib/ruby/gems/1.9.1/gems/railties-> 3.1.1 / lib / rails / initializable.rb：54：in run_initializers' from C:/Ruby192/lib/ruby/gems/1.9.1/gems/railties->3.1.1/lib/rails/application.rb:96:in initialize！'     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 >'     来自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！'     来自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'     来自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

我在命令提示符下运行它，同时位于我之前创建的rails应用程序的目录中。任何帮助将不胜感激！

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的文件权限
