在我的项目中,我使用了设计宝石。以前,我将这个宝石用于其他项目,但没有问题。但是现在当我尝试生成这个命令时
>> rails generate devise:install
我收到此错误:

但不知道为什么? 这是我的gemfile:
source 'http://rubygems.org'
gem 'rails', '4.0.4'
gem 'sqlite3'
gem 'sass-rails'
gem 'uglifier'
gem 'coffee-rails'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder'
gem 'sdoc', group: :doc
gem 'carrierwave'
gem 'bootstrap-sass'
gem 'devise'
这是我的development.rb文件:
Rails.application.configure do
config.cache_classes = false
config.eager_load = false
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
config.action_mailer.raise_delivery_errors = false
config.active_support.deprecation = :log
config.active_record.migration_error = :page_load
config.assets.debug = true
config.assets.raise_runtime_errors = true
end
