这是我的Gemfile:

source 'https://rubygems.org'
ruby '2.1.5'

gem 'rails', '4.1.8'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0',          group: :doc
gem "paperclip", "~> 4.3"
gem 'bootstrap-sass', '~> 3.3.5'
gem 'jquery-ui-rails'
gem 'jquery-turbolinks'
gem 'sprockets'
gem 'capybara-webkit'
gem "chartkick"

group :development do
  gem 'sqlite3'
end

group :production do
  gem 'pg'
  gem 'rails_12factor'
end

group :development, :test do  
  gem 'guard-rspec'  
  gem 'factory_girl_rails'  
  # gem 'pry-rails'  
  gem 'rspec-rails'  
  gem 'selenium-webdriver'
  gem 'capybara'  
end

Answer 1

移动gem 'capybara-webkit'到:development, :test组,它在生产没有必要:

许多应用依赖于具有本机扩展的gem,需要在部署目标上进行编译.

  gem 'guard-rspec'

  # gem 'pry-rails'  
  gem 'rspec-rails'

  gem 'selenium-webdriver'
  gem 'capybara'
