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

Question

我对制作简单的 .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:

C:/Ruby193/lib/ruby/gems/1.9.1/gems/ruby-ole-1.2.11.5/lib/ole/storage/base.rb:62:in write_nonblock': Bad file descriptor - test.xls (Errno::EBADF)

因为ruby-ole 1.2.11.5不支持windows平台，更多细节:ruby-ole issue

您可以使用 ruby​​-ole 1.2.11.4 来避免这个问题。

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