If you are using the official documentation and created the project using npx create-medusa-app

and if your folder structure is similar to below

/my-medusa-store
  /storefront // Medusa storefront starter
  /backend // Medusa server
  /admin // Medusa admin

Run the medusa commands inside the /backend folder. This solves my issue

DIFFERENT SOLUTION FOR THOSE ASKING FOR HELP WITH medusa user ...

for those who is getting error while running medusa user ..., just change your terminal folder to ./my-medusa-store and than run same script. Problem is that medusa script tryng to run some packages locally from deps and in medusa-admin/node_modules are missing those deps. Is even written in the doc above the script

To create a new admin user from the command line, run the following command in the directory holding your Medusa server:

Happy codding

FWIW I ran into this error too when setting up MinIO. TLDR I think (in my case) it’s a conflict with yarn v3+. I fixed the error by undoing the yarn add and re-installing with npm.

Steps to reproduce: (MacOS and node v16)

Fresh install with medusa new ...
Per the quickstart guide run yarn add medusa-file-minio (in my case with yarn v3.2.3), and add MinIO stuff to .env and medusa-config.js.
Run medusa develop
The error appears: “TypeError: cmd is not a function…”

To fix the error:

Run yarn remove medusa-file-minio
Manually delete all the files yarn added
Run npm install medusa-file-minio
Run medusa develop
The server starts up. No error.

Getting the same error on “medusa user”, works fine on “medusa” alone.

That worked, I had to use a module called n to get it to use the latest node instead of stable. Thanks
