Question

我的脚本有问题，它生成简单的.xls文件并将数据写入一个单元格。这是一个简单的代码：

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

但它引发了错误：

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

Answer 1

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

Answer 2

我之前见过这些。首先验证您是否可以写入该文件的位置。我的猜测是文件已在Excel中打开，或者您的防病毒软件阻止了“威胁”。
