Missing Ruby Version on ASDF

Question

I am trying to install Ruby 2.7.7 via asdf but the latest version appears to be 2.7.6. Anyone happen to know how to support a new Ruby version on asdf?

Available Ruby 2.7.x versions

Tried installing Ruby 2.7.7, expected version to be available.

The asdf-ruby plugin uses ruby-build to actually build Ruby versions. To be able to install new Ruby versions, ruby-build needs to be updated.

You can set the desired ruby-build version by setting the ASDF_RUBY_BUILD_VERSION environment variable to the desired version before invoking asdf.

Alternatively, you can also update your asdf-ruby plugin to use the current ruby-build version on every invocation as they have updated the plugin to use the current ruby-build version by default in asdf-vm/asdf-ruby#317.

This can be done with either

asdf plugin update --all

or

asdf plugin update ruby

to just update the ruby plugin.
