Ruby Deviate出错-无法运行rails或任何Deviate命令

我最近添加了gem'designe'，但突然间，我无法再运行rails s或任何designe命令而不看到以下错误消息：

`c:3:in rescue in execute_if_updated': Rails::Application::RoutesReloader#execute_if_updated delegated to updater.execute_if_updated, but updater is nil: #<Rai

Routes.rb

---

也许你可以换到rails edge

gem 'rails', github: 'rails/rails'
gem "devise", "~> 3.0.1"

---

（）

您可以添加

Gemfile

和

routes.rb

吗？编辑以添加文件。如果格式不好，我深表歉意。

Omrails::Application.routes.draw do
  devise_for :installs
  # You can have the root of your site routed with "root"
  get 'about' => 'pages#about'
  root :to => 'pages#home'
end

gem 'rails', github: 'rails/rails'
gem "devise", "~> 3.0.1"
