Hey all - setup question. I'm trying to follow along this course by Laurie Voss: https://learn.deeplearning.ai/courses/javascript-rag-web-apps-with-llamaindex/lesson/2/getting-started-with-rag
In the step with this code:
import {
Document,
VectorStoreIndex,
SimpleDirectoryReader
} from "npm:llamaindex@0.1.8"

I get this syntax error for { after import.
Am I missing something in the setup?
Thanks
