the post from self-creative worked for me. sorry to necro a dead thread but i felt that needed to be said.

Thanks self-creative!

Thanks self-creative! Home brew managed to delete a project with my .git when I tried to commit. It installed poorly and reading through this thread was daunting. Glad I read to the bottom.

Thanks, @self-creative! You saved my time a lot.

For me this command worked! 🍺
