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位的一切。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

答案 0 :(得分：0)
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irb中的此连接执行任何操作，以测试您的ibm_db gem，例如，如果它正常工作。
