You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: show.rb
    path of file: ./repos/artichoke/artichoke-backend/vendor/ruby/lib/bundler/cli
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Bundler
  class CLI::Show
    attr_reader :options, :gem_name, :latest_sp
    
    def run
      Bundler.ui.silence do
        Bundler.definition.validate_runtime!
        Bundler.load.lock
      end

      if gem_name
        if gem_name == "bundler"
          path = File.expand_path("../../../..", __FILE__)
        else
          spec = Bundler::CLI::Common.select_spec(gem_name, :regex_match)
          return unless spec
          path = spec.full_gem_path
          unless File.directory?(path)
            return Bundler.ui.warn "The gem #{gem_name} has been deleted. It was installed at: #{path}"
          end
