The latest build image (in beta) doesn’t default to a Ruby version that’s already installed, so if you have no use for Ruby, you need to wait on it to install for no reason:
8:52:38 AM: Attempting ruby version 2.7.1, read from environment 8:52:39 AM: 8:52:39 AM: ** WARNING ** 8:52:39 AM: Using custom ruby version 2.7.1, this will slow down the build. 8:52:39 AM: To ensure fast builds, set the RUBY_VERSION environment variable, or .ruby-version file, to an included ruby version. 8:52:39 AM: Included versions: 2.6.2 2.7.2
I solved it by setting an env var of
RUBY_VERSION=2.7.2 in the admin UI and this behaves as is probably desired. Would be good if the image defaulted to a version it already has? Maybe something else I’m using is causing this? Can provide site detail out of band if it’s needed.
