Ruby Spreadsheet：錯誤的文件描述符 - test.xls（Errno :: EBADF）

Question

我有腳本的問題，生成簡單的.xls文件並將數據寫入一個單元格。 這是簡單的代碼：

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

但它引發了錯誤：

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) from C:/Ruby193/lib/ruby/gems/1.9.1/gems/ruby-ole-1.2.11.5/lib/ole/storage/base.rb:62:in initialize'

Answer 1

因為ruby-ole 1.2.11.5不支持windows平台，更多細節： ruby-ole問題

你可以使用ruby-ole 1.2.11.4來避免這個問題。

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

Answer 2

我以前見過這些。 首先驗證您是否可以寫入該文件的位置。 我的猜測是文件已在Excel中打開，或者您的防病毒軟件阻止了“威脅”。
