ruby-on-rails - '<module:ActiveRecord>':未初始化的常量CarrierWave::Mount(NameError)

我在尝试运行rspec时遇到此错误，我正在使用：
rails 4.2.4ruby 2.2.2carrierwave 0.10.0
我能做什么？！

最佳答案

我通过在carrierwave orm文件中请求application文件后请求config/environment.rb来解决这个问题。
require File.expand_path('../application', __FILE__)require 'carrierwave/orm/activerecord'
