Upgrade Ruby version? #58
Description
I am new to Ruby, so please tell me if I there are any gotchas around running old versions.
When I run bundle install --without production, I get the error message Your Ruby version is 2.5.1, but your Gemfile specified 2.3.1.
Should I try to downgrade my Ruby version or is it reasonable to keep the project’s Ruby version up-to-date? (latest version is currently: 2.6.1)
