Hoping someone can help me. I'm running through this guide on Stack Reference, <https://github.com/pulumi/examples/tree/master/aws-py-stackreference>

When I create *department* under the *company* directory, it won't allow me to create `pulumi stack init dev` as it says it already exists. What am I doing wrong?

The stack name (e.g. `dev`) must be unique to the project - e.g. `aws-py-stackreference-company`, `aws-py-stackreference-department`, etc.

The project name is determined by the `Pulumi.yaml` file that is in the directory where you run `pulumi stack init ...`.

Can you elaborate on _"When I create *department* under the *company* directory..."_ ?

To create a `dev` stack for each project, you would `pulumi stack init dev` from _each_ of the company, department, and team directories.

"Can you elaborate on _"When I create *department* under the *company* directory..."_ ?"

Hi <@UDEJ1F5SQ>, So i'm creating the directory structure like so:
Company
     |_
        Department

Then running `pulumi new aws-python` in each directory.

I guess you are using `pulumi login -local`. In this case, all stacks name should be unique cross all pulumi projects.
It’s not the case if you use the pulumi backend
