Devise错误-无法运行rails或任何devise命令

Question

我最近添加了gem ' devise‘，但是突然之间，我再也无法运行rails s或任何devise命令了，除非看到这个错误消息：

`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

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

也许你可以转向rails的边缘。

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