I need help.

So I am cd’ing to buildstuff and src then doing npm run build

It is a Python repl, but I need to use npm/node

Svelte code:

<script>
	let name = 'world';
</script>

<h1>Hello {name}!</h1>

Does anyone know how to help? I see no errors in the code.. so I am curious why it does not work.
