AASM状态机已经在我的应用程序中启动并且正在运行，但是我想为我的模型规范文件使用AASM RSpec匹配器。
对于我的Gemfile，我已经安装了以下软件（当然是简短列表）：
➜ ✗ gem list
*** LOCAL GEMS ***
aasm (5.0.1, 4.0.8)
capybara (2.6.2)
factory_girl (4.5.0)
factory_girl_rails (4.5.0)
faker (1.7.3)
rspec (3.4.0)
rspec-collection_matchers (1.1.2)
rspec-console (0.6.1)
rspec-core (3.4.2)
rspec-expectations (3.4.0)
rspec-its (1.2.0)
rspec-mocks (3.4.1)
rspec-rails (3.4.2)
rspec-rerun (1.1.0)
rspec-support (3.4.1)
对于AASM doc，我在我的spec_helper.rb文件中添加了require 'aasm/rspec'：
require 'capybara/rspec'
require 'faker'
require 'factory_girl'
require 'database_cleaner'
require 'shoulda/matchers'
require 'paperclip/matchers'
require 'factory_girl_association_callbacks'
require 'rspec_controller_context'
require 'capybara/poltergeist'
require 'capybara/dsl'
require 'site_prism'
require 'email_spec'
require 'paper_trail/frameworks/rspec'
require 'aasm/rspec'
在将任何AASM Rspec匹配器添加到我的规范文件之前，我想确保设置正确。所以我只在文件上运行RSpec并收到以下错误：

是的，我的规格文件的顶部是require 'rails_helper'。
我有一种感觉，我真的很想念它。感谢所有帮助，因为我希望能够使用transition_from，have_state，allow_event和allow_transition_to。预先感谢。
