Ruby on Rails - How to set the default ruby version in my project?

Question

I have a ruby on rails 5.2.4 app and in the: app/site/shared/bundle/ruby I have the following folders: 2.2.0 and 2.3.0

In my: app/site/current , if I run: ruby -v it shows: Ruby 2.2.3

But if I run: rvm use 2.6.6 --default (or without default), the ruby version is changed, but on the next ssh connection the ruby version is 2.2.3 again.How can I add Ruby 2.6.6 to the app/site/shared/bundle/ruby folder and what should I change in order to remember the ruby default version as 2.6.6 ?

Answer 1

I found the solution:

create a file: .ruby-version in your app's current folder

Inside this folder add: ruby-2.6.6 (or whatever ruby version you want to use as default).
