Ruby roo 加载错误:无法加载此类文件 - 电子表格/注释

Question

尝试加载xls文件并得到此错误。有控制台日志：

irb(main):001:0> require 'roo'
=> true
irb(main):002:0> a = Roo::Excel.new('/home/a.xls')
LoadError: cannot load such file -- spreadsheet/note

请帮助解决此问题

同样，当我尝试需要电子表格时，我得到同样的错误

require 'spreadsheet'

但是这个模块是安装的

$ gem list | grep spreadsheet
spreadsheet (0.9.2)

Answer 1

尝试将"电子表格"gem 的版本修复为"0.9.0"。

在我的情况下添加

gem "spreadsheet", "0.9.0"

就在罗宝出招之前。
