Same problem for me.

Missing the component REPL.svelte.... but it is there.

Please update instruction on how to run it if possible :)

I belive @thebells1111 developed on a case-insensitive filesystem.

On my linux I "renamed" the culprits and it works:

mv src/Components src/components
mv src/components/REPL src/components/Repl
