In situations where use-package doesn’t get loaded because all packages are already installed, but it is still used for configuration, you can run into issues caused by perconal-keybindings being void:
⛔ Error (use-package): consult/:catch: Symbol’s value as variable is void: personal-keybindings
Explicitly requiring bind-key resolves this issue.
Requiring it in use-package’s :init section makes sure it’s loaded before the bindings are created, while still keeping it close to the configuration it’s required for.
A declaration for Consult might look like this, for example:
(use-package consult :ensure t :init (require 'bind-key) :bind (("C-x p b" . consult-project-buffer)))
