Fixnum is deprecated - when I run rake db: seed
In my project whenever I run the rake db:seed command I get these messages
How could I solve those warnings?
Solution
Ruby version 2.4.0 (~Dec 2016) unified Fixnum and Bignum into Integer and deprecated Fixnum. You're probably using ruby version 2.4.0 or later. Your version 1.13.2 of the roo gem is older than that (~Dec 2013) and is using Fixnum. Thus you get the warning.
Your code will still run fine for now with the warning, but if you want to get rid of it, you could upgrade your roo gem. The latest version is 2.8.3 (Feb 2020). If you do upgrade, you may have some code changes to do depending upon what may have changed in the newer version of the gem.
