И это мой 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

Move gem 'capybara-webkit' к :development, :test группе, то нет необходимости в производстве:

Many apps depend on gems with native extensions that need to be compiled on the deployment target.

Ref

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

Answer 2

Попробуйте изменить с этим в файле гем:

gem "capybara-webkit", github: "thoughtbot/capybara-webkit", branch: "1.0"
