Hi! I am trying to run through the https://supabase.com/docs/guides/with-svelte and when I run npm run dev I keep getting the error

> svelte-app@1.0.0 dev /Users/bob/Documents/dev/javascript/svelte/supabase-svelte
> rollup -c -w

sh: rollup: command not found

my rollup.config.js looks like this

The error is saying you don't have rollup installed on your system, so it cant find the rollup command.
