Variable: use-package-ensure-install-during-compile
use-package-ensure-install-during-compile is a variable defined in
use-package-ensure.el.gz.
Value
nil
Documentation
If non-nil, :ensure causes installation during compilation (deprecated).
If nil, package installation happens only at run-time, which is much more
sane since compilation is usually presumed to be a "pure function"
with no other side-effects than saving the resulting .elc file.
Probably introduced at or before Emacs version 32.1.
