【问题描述】：

我对制作简单 .xls 文件并将数据写入一个单元格的脚本有疑问。这是简单的代码：

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

但它会引发错误：

【解决方案1】：

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

你可以使用 ruby-ole 1.2.11.4 来避免这个问题。

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

【解决方案2】：

我以前见过这些。首先验证您是否可以写入该文件的位置。我的猜测是文件已经在 Excel 中打开，或者您的防病毒软件正在阻止“威胁”。
