The del_dir method has no problem.

The problem is due to see_me method.
Modify see_me something like this will work.

  def see_me
    if File.exist?("#{@dirname}")
      cwd = Dir.pwd
      begin
        Dir.chdir("#{@dirname}")
        puts Dir.pwd
      ensure
        Dir.chdir(cwd)
      end
    else
      puts "This directory #{@dirname} is not exist!"
    end
  end
