Where are

project name

stored when running the Pulumi CLI? I'm trying out Pulumi and keep getting

Sorry, 'x' is not a valid project name. A project with this name already exists

when creating a new project and give name x. Where is this stored so I can obliterate it? Re-installed Pulumi CLI and deleted from the web UI but still getting this

maybe there's local cache to clear?

Yes. I did

rm /home/$USER/.pulumi

and re-installed. Cheers
