Ruby roo LoadError：無法加載此類文件 - 電子表格/注釋

Question

嘗試加載xls文件並獲取此錯誤。 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

    from (irb):2

請幫忙解決這個問題

此外，當我嘗試需要電子表格時，我得到相同的錯誤

require 'spreadsheet'

但是這個模塊是安裝的

$ gem list | grep spreadsheet
spreadsheet (0.9.2)

Answer 1

嘗試將“電子表格”gem的版本修復為“0.9.0”。

在我的情況下添加

gem "spreadsheet", "0.9.0"

就在roo gem之前做了一招。
