spack install package only fails #15196
Description
This issue was reported on slack earlier today by scottwittenburg. The problem occurs during their two-pass install process:
spack install --cache-only --only dependencies <path-to-spec.yaml>
spack install --no-cache --only package <path-to-spec.yaml>
which results in :
==> [2020-02-24-21:20:30.689327, 754] Error: Detected uninstalled dependencies for ncurses: {'pkgconf'}
==> [2020-02-24-21:20:30.689430, 754] InstallError: Cannot proceed with ncurses: 1 uninstalled dependency: pkgconf
==> [2020-02-24-21:20:30.689467, 754] Error: Cannot proceed with ncurses: 1 uninstalled dependency: pkgconf
This issue can be reproduced by attempting spack install --only package <spec> for any package.
