Could not find generator cucumber:install

Could not find generator cucumber:install.

I fix this by installing cucumber-rails gem instead of the cucumber gem.

gem install cucumber-rails

or you can put it in your bundle file.

source 'http://rubygems.org'
.
.
.
group :test do
  gem 'rspec', '2.5.0'
  gem 'capybara'
  gem 'cucumber-rails'
end

rails generate cucumber:install --capybara
