当我运行代码时：
require 'rubygems'
require 'win32ole'
require 'watir-webdriver'
require "spreadsheet"
Spreadsheet.client_encoding = 'UTF-8'
book = Spreadsheet::Workbook.new
book = Spreadsheet.open 'C:\\Users\\mndd\\Desktop\\Cucumber\\Watir\\demo (2)\\demo\\Test.xls'
我有相同错误的先前查询的所有解决方案（更新Gems，重新安装电子表格GEM等），但无法解决它。我做错了什么？
