当我使用下面的代码时,我收到以下错误消息: can't convert StringIO into String (TypeError)

array_of_lines = []
Zip::ZipInputStream::open(open("URL for zipped file", "rb")) do |io|
  file = io.get_next_entry
  puts "Downloading file #{file}"
  array_of_lines = io.readlines
  print "Downloaded ", array_of_lines.count, " elements.", "\n"
end

有人能帮我吗？预先感谢.
