Rails / Rspec：未初始化的常量Rails（NameError）

Question

当我运行bundle exec rake spec时，我一直遇到此错误：uninitialized constant Rails (NameError)

这是我的gemfile：

group :development do
  gem 'guard-rspec'
  gem 'guard-spork'
end

group :development, :test  do
  gem "debugger-ruby_core_source", "~> 1.2.2"
  gem 'debugger' 
  gem 'faker'
  gem 'rspec-rails' 
  gem 'factory_girl_rails'
  gem 'spork-rails', "~> 3.2"
  gem "database_cleaner", "~> 0.9"
end

group :test do
  gem 'capybara' 
  gem 'guard-rspec' 
  gem 'launchy'
  gem "shoulda-matchers", "~> 2.0"
  gem "selenium-webdriver"
  gem "rspec-sidekiq"
end

我无法弄清楚为什么会这样......

你要
