Ruby电子表格：错误的文件描述符-test.xls（Errno:：EBADF）

我对生成简单的.xls文件并将数据写入一个单元格的脚本有问题。下面是简单的代码：

require 'spreadsheet'

class Filter
  def filter
    @excel = Spreadsheet::Workbook.new
    @sheet = @excel.create_worksheet

    @sheet[0, 0] = "test"
        @excel.write 'test.xls'
  end
end

f = Filter.new
f.filter

但这会引起错误：

我以前见过这些。首先验证是否可以写入该文件的位置。

我的猜测是该文件已经在Excel中打开，或者您的防病毒软件正在阻止“威胁”。

因为ruby ole 1.2.11.5不支持windows平台， 更多详情：

可以使用ruby ole 1.2.11.4来避免此问题

require 'rubygems'
gem 'ruby-ole','1.2.11.4'
require 'spreadsheet'
