在ruby中安装DB2

Question

How can i connect with db2 AS400 in ruby without using jruby. I am trying to install ibm_db gem in console , but it's throwing error like below

    current directory: C:/Ruby25-x64/lib/ruby/gems/2.5.0/gems/ibm_db-.0.0/ext
    C:/Ruby25-x64/bin/ruby.exe -r ./siteconf20190531-15036-er6nbm.rb extconf.rb Detected 64-bit Ruby

    Environment variable IBM_DB_HOME is not set. Set it to your 
    DB2/IBM_Data_Server_Driver installation directory and retry gem install.

Answer 1

The doc for the gem seems to say that only 32bit ruby is supported on Windows.
