Ruby Versions Support
Important: These docs are for the outdated Jets 5 versions and below. For the latest Jets docs: docs.rubyonjets.com
Jets supports Ruby 2.5 and Ruby 2.7. Patch variants of it should work.
Using Different Ruby Versions
Generally, Jets detects the current version of ruby that is installed on your system and will use that one. If you want to use ruby 2.7, switch to it and deploy with it.
It is recommend that you use rbenv or rvm to switch to the targeted ruby version and deploy. Here’s an example with rbenv.
rbenv local 2.7.2
jets deploy
Here’s another example with rvm.
rvm use 2.5.8
jets deploy
Bypass Ruby Version Check
Jets checks your current ruby version and makes sure its a version that Jets supports. If you would like to bypass this check, you can set JETS_RUBY_CHECK=0. You can can also set a config.
config/appplication.rb
Jets.application.configure do
config.ruby.check = false
end
