Unable to concretize environment if python isn't installed yet #13529
Description
Spack Environments crashes when you try to concretize/update an environment that contains Python, but Python hasn't been installed yet.
Steps to reproduce the issue

$ spack installError Message

concretization: together@becker33 I believe this is related to #13249. Spack is trying to run setup_run_environment even for packages that are not yet installed, causing this crash.
