Rbenv & available ruby versions in stack

[Ian.Magarzo]

After the release of Mac OS Catalina I’ve started to use rbenv again.

Some workflows which use Gems are failing in Bitrise, is it possible to use rbenv to set a specific version of Ruby for each workflow?

I’m using the 2.6.5 though, I see by default, in the Stack is used the 2.6.3, how would I be able without rbenv to tell Bitrise to use the 2.6.5 already included in “osx-xcode-11.2.x”

@Ian.Magarzo assume you might of solved this by now but if not… I was able to bump the version of Ruby used in one of my projects by added a .ruby-version file with the version I wanted to use i.e 2.6.5.

The gotcha here is that rbenv in the Vagrant might not have 2.6.5 as a known version to install. If this is the case you should add a brew install task to install rbenv and make sure update/upgrade is set to yes. This will also update ruby-build which will update the list of installable Rubies.

Just a note: rbenv is now preinstalled on all Mac stacks, so in most cases no brew upgrade required at all, but if it would be (if you’d want to use a future ruby version) this should do the trick:

brew upgrade rbenv ruby-build
