试试这个：

Sample::Application.routes.draw do
   match '/help' => 'static_pages#help'
   match '/contact' => 'static_pages#contact'
   match '/about' => 'static_pages#about'
   root :to => 'static_pages#home'
end

可能你在 _header 文件中有错字，因为每个错误都有它，再次检查 _header 文件，如果是这种情况，你应该在运行 rails server 并尝试访问页面时遇到同样的错误。
