我正在使用Rails 4.2.7,只是将电子表格gem添加到我的Gemfile
gem 'spreadsheet'
可悲的是,当我对以“.xls”
结尾的文件执行此调用时 book = Spreadsheet.open file_location
我收到以下错误。不幸的是,不能以另一种Excel格式重新保存此文档(我甚至没有在我的计算机上安装Excel)。我该如何解析这个xls文件?如果能解决问题,我愿意使用另一个宝石。

我尝试使用电子表格时遇到了一些问题。那是一段时间以前,所以我不记得究竟发生了什么,但我相信这是一个类似的OLE错误。从那时起它也被更新了。但是,既然你提到你会考虑另一个宝石,我转而使用roo它对我来说效果很好。一个非常强大的好处是它可以处理许多不同的格式,而不仅仅是Excel兼容。
