Rake Task doesn't work with Rspec 3.6.0

[schneems]

I'm getting this error:

$ bundle exec rake spec:part[$(($CI_NODE_INDEX + 1)),$CI_NODE_TOTAL]
Running part 1 of 16 groups
rake aborted!

Tasks: TOP => spec:part
(See full trace by running task with --trace)

Based on #3 I copied and pasted the contents of the rake file into the bottom of my Rakefile.

require 'rspec/core/rake_task'
require 'rspec/parts'

if defined?(RSpec)
  namespace :spec do
    desc 'Run part M of N specs'
    RSpec::Core::RakeTask.new(:part, :part, :groups) do |task, task_args|
      config = Rspec::Parts.config

      groups = task_args[:groups].to_i == 0 ? config.default_number_of_parts : task_args[:groups].to_i
      part = (task_args[:part].to_i == 0 ? 1 : task_args[:part].to_i)
      part_index = part - 1

      puts "Running part #{part} of #{groups} groups"

      file_list = Rspec::Parts::FileList.from(glob: config.spec_directory_glob, groups: groups, part: part_index)
      config.file_list_exclusions.each do |exclusion|
        file_list.exclude(exclusion)
      end

      task.rspec_opts = config.rspec_opts
      task.pattern = file_list
    end
  end
end

When I try to execute a test I get the error at top. I'm guessing this has to do with a compatability issue with certain versions of rspec.
