如何修复“电子表格”gem 中的错误（未知代码页 0x906c）？

Question

我需要从 xls 文件中获取涉及 gem 'roo' 的信息。 当我尝试读取文件时，出现错误。

请帮助修复此错误！

我的代码：

require 'roo'
require 'spreadsheet'
require 'open-uri'

x = Roo::Excel.new("http://EXAMPLE.COM/EXAMPLE.xls")
x.cell 31,'F'

Answer 1

就我而言，我必须使用电子表格 gem 处理代码页问题。经过一番研究，我发现这是文件本身的一种格式，取决于它的某些特征。

以下是 Gem 本身的一些信息：

https://github.com/zdavatz/spreadsheet/blob/master/lib/spreadsheet/excel/internals.rb#L15

我的解决方案是获取原始文件并将其发送到在线转换器。从那里将其转换为 xls（无论它是否已经是 xls 格式）。

希望有帮助！
