【问题描述】：

我正在尝试安装“ibm_db”gem 并验证安装。我在 Windows 7 上运行，我正在尝试使用 32 位来处理一切。我需要连接的数据库是 IBM iSeries 上的 DB2。以下是我目前使用的步骤。

•   gem install “ibm_db”
•   irb
•   require “ibm_db”

我得到以下结果：

c:\Users\Bob\RubymineProjects\beginruby>gem install ibm_db

【问题讨论】：

你读过这个帖子了吗：groups.google.com/group/ibm_db/browse_thread/thread/…
谢谢，菲特。我看着那个。那里提到的一些事情让我相信它不适用于我的情况。我没有使用 python 或 informix，而且这个问题似乎没有得到解决。在我正在阅读的关于在我的 iSeries for rails 和/或 ruby 上安装 ibm_db for DB2 的信息中，没有任何地方提到过关于 ibm_db...egg 的任何内容。我还下载并安装了 IBM 的数据服务器驱动程序包。 IBM 为 ruby 安装 ibm_db 的说明说不需要在 Windows 上更改环境变量。任何更多的想法将不胜感激。谢谢

【解决方案1】：

放入你的 irb 控制台（windows）：

require 'mswin32/ibm_db'

conn = IBM_DB::connect("DATABASE","db2admin","password")

当然，您可以使用来自 irb 的此连接进行任何操作，以测试您的 ibm_db gem，例如它是否正常工作。
