librarian-chef requiring ruby2.3 fails to install on ruby2.4

Question

I am trying to install a vagrant plugin "librarian-chef". When I run the command vagrant plugin install librarian-chef, I get the error:

Bundler, the underlying system Vagrant uses to install plugins, reported an error. The error is shown below. These errors are usually caused by misconfigured plugin installations or transient network issues. The error from Bundler is:

chef-zero requires Ruby version >= 2.3.1.

• Why does this requirement break the install?
• How do I make sure my setup meets what this needs?

Details of my setup

I have ruby-2.4.0p0 on a Macbook installed under RVM. This is my only Ruby on this machine.

For reference purposes, I am trying to get started with the plos/lagotto repo.

Answer 1

I don't see anything in that repo telling you to install anything related to librarian. Librarian-chef has been basically abandoned by the community, but if you did want to use it for some reason the plugin to install is vagrant-librarian-chef, not librarian-chef.
