我试图安装“ibm_db”gem并验证安装。我在Windows 7上运行，我试图使用32位的一切。我需要连接到的数据库是IBM iSeries上的DB2。以下是我目前使用的步骤。要求ibm_db指定的模块找不到
• gem install “ibm_db”
• irb
• require “ibm_db”
我得到如下结果：
c:\Users\Bob\RubymineProjects\beginruby>gem install ibm_db

您是否阅读过此主题：https://groups.google.com/group/ibm_db/browse_thread/thread/880753ad99d399f7/9410202178da063b?#9410202178da063b – phoet
谢谢，Phoet。我看了看。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，并且该问题似乎没有解决。没有在我正在阅读的关于在iSeries for rails上安装ibm_db for DB2的信息和/或ruby是否提及有关ibm_db ... egg的所有信息。我还下载并安装了IBM的数据服务器驱动程序包。 IBM针对ruby安装ibm_db的说明指出，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 –
