Device.rb is missing a require in ruby lib

/Users/xxx/.rvm/gems/ruby-2.1.2/gems/appium_lib-5.0.0/lib/appium_lib/device/device.rb:5:in `module:Device’: uninitialized constant Appium::Device::Forwardable (NameError)

Fix we did locally is added : require ‘forwardable’

with in device.rb and seems fine could this be fixed ?? or let us know what we are missing apart from bundle install.

Did you require appium_lib? That is where forwardable is required.

Also I recommend updating to 5.0.1, a bug related to awesome_print was fixed.
