[support]: E4S 23.02 Cache: 'py-hatch-nodejs-version' not found

[eugeneswalker]

Vincente Bolea, a Senior R&D Engineer at KitWare, brought to our attention, by direct communication, an issue affecting the use of E4S 23.02 build cache for users running Spack v0.19.1 with the concretization:reuse:true option. We were able to reproduce the issue on multiple systems and are now in the process of coordinating a solution with the Spack team.

Until this is resolved, users of Spack v0.19.1 (i.e. checkout at v0.19.1) are encountering concretization errors similar to the following error when they also have concretization:reuse:true set.

$> spack mirror add E4S https://cache.e4s.io/23.02
$> spack buildcache keys -it

You may need to run 'spack clean -m'.

We filed a corresponding issue with the Spack repository to track progress:

The workaround for this, for the moment, is to set concretizer:reuse:false. We will post updates here as we work towards a solution that allows users to have concretizer:reuse:true.

Thanks to @tgamblin for the following PR which resolves this issue. Once merged, users will be able to take advantage of concretizer:reuse:true in conjunction with E4S build caches!
