There are some inconvenient Gem dependencies. Resolve them by adding/modifying these lines in your Gemfile:
gem 'guard-livereload', '>= 2.5.2', require: false # Fixes a security issue
gem 'listen', '< 3.1' # 3.1 requires Ruby 2.2.5
It is not possible to install guard-livereload 2.5.2 on Ruby 1.8.7 because it depends on guard 2.8, which requires Ruby 1.9.
