undefined method 'tmpdir' for Dir:class

Created by: thedarkside

i am running ruby 2.3.1 and it seems that capistrano-git-copy does not require 'tmpdir' which leads to that error: undefined method 'tmpdir' for Dir:class. Placing that require statement in deploy.rb before require 'capistrano/git_copy' solves this but it would be much nicer if it would be required where it should be: capistrano-git-copy-1.3.0/lib/capistrano/git_copy/scm.rb:132
