爲什麼我從Rails的generate中得到「no such file」錯誤信息？

Question

爲什麼我得到一個「沒有這樣的文件」的錯誤消息，當我運行這個命令？：

$ rails generate controller Pages home contact 
c:/Users/Michele/rails_projects/sample_app/config/application.rb::in 'require': no such file to load -- sprockets/railtie (LoadError) 
     from c:/Users/Michele/rails_projects/sample_app/config/application.rb:8 
     from c:/RailsInstaller/Ruby1.8.7/lib/ruby/gems/1.8/gems/railties-3.0.11/ lib/rails commands.rd:15 
     from c:/RailsInstaller/Ruby1.8.7/lib/ruby/gems/1.8/gems/railties-3.0.11/ lib/rails commands.rd:15 
     from script/rails:6:in 'require' 
     from script/rails:6

看起來你沒有所有的Rails安裝所需的庫。 嘗試運行gem install rails命令

或者，也許，你有博肯Rails應用程序樹 - 嘗試與rails new my_app_name
