Ruby on rails rails生成错误：安装失败，出现“错误”；无法加载发电机“；

我试图安装Cucumber，但

rails g Cucumber:install

在终端中显示错误：

[WARNING] Could not load generator "generators/cucumber/install/install_generator". Error: uninitialized constant Cucumber::Generators::InstallBase::Config.

以下是我的Gemfile中包含cucumber rails的部分：

group :test do
    gem 'faker'
    gem 'capybara'
    gem 'guard-rspec'
    gem 'cucumber-rails', :require => false
    gem 'database_cleaner'
    gem 'selenium-webdriver'
    gem 'gherkin'
    gem "launchy", "~> 2.1.2"
end

这是我的全部档案：

可能是弹簧启动，无法加载发电机。试一试
