Meteor version error pushing apps

[krstffr]

The buildpack worked fine until this morning, when I started getting this error when pushing apps to heroku. (Haven't changed anything at all in the app.)

   Done installing smart packages

   Building meteor bundle
   You must specify a Meteor version with --release when you work with this
   project. It was created from an unreleased Meteor checkout and doesn't
   have a version associated with it.

   You can permanently set a release for this project with 'meteor update'.
   tar: /app/tmp/repo.git/.cache/bundle.tar.gz: Cannot open: No such file or directory
   tar: Error is not recoverable: exiting now
   tar: Child returned status 2
   tar: Exiting with failure status due to previous errors
