问题
I'm running Ruby 2.6.3p62 32-bit on Windows 10 64-bit. I installed it using the Ruby Installer. I successfully installed the gem 'ibm_db' without any errors. I downloaded the DB2-clidriver from http://public.dhe.ibm.com/ibmdl/export/pub/software/data/db2/drivers/odbc_cli/nt32_odbc_cli.zip, unzipped it an set the environment variable IBM_DB_HOME to its location. In addition, I added IBM_DB_HOME\bin to the PATH variable. When requiring the ibm_db I get the following error:
C:\Users\myuser\Programs\Ruby26\bin>ruby -e "require 'ibm_db'"
Traceback (most recent call last):

The file mentioned in the last line

does exist.

Your question may be better suited to the Github issues page for the ibm_db gem, because your question concerns configuration and does not concern either Ruby programming , or programming for Db2.
In particular see: https://github.com/ibmdb/ruby-ibmdb/issues/83
It appears that the ibm_db gem may not yet support your version of Ruby on your operating-system platform, but it may support an older version of Ruby.
