Error "Symbol’s value as variable is void: helm-source-projectile-projects"

[svenpanne]

helm-projectile had an incompatible API change yesterday: bbatsov/helm-projectile@9db7976, so helm-source-projectile-projects is gone, breaking various project-related functionality. It's still used in layers/+completion/helm/packages.el, so this has to track the API change, I guess.

The change bbatsov/helm-projectile@9db7976 has issue bbatsov/helm-projectile#184 , that mean helm-projectile currently not work from its self.

Wait for the upstream actions. Then we can make some changes to work with the latest one.

This is now fixed upstream in bbatsov/helm-projectile#182, and the fix should appear on MELPA soon.
In the meantime, one can either roll back the package update in Spacemacs, or add the following to dotspacemacs-additional-packages and update to get the new version a few minutes or hours sooner:

(helm-projectile :location (recipe :fetcher github :repo "bbatsov/helm-projectile"))

(Alternatively, switch to the compleseus layer 😉)

This is an instance where a delayed package mirror (as suggested in #16775) would likely have prevented the problem.

[fnussbaum]

The update is available on MELPA now, so updating packages should fix the issue.

Confirmed! :D
