Cant import scss from node_modules

[DLOspreyFs]

I'm trying to make the case for switching over to snowpack for a greenfield project, however we currently use a common styles package in all of our applications which I can't seem to successfully import.

The styles are hosted at a private npm org, at the top level we have a scss file (resets.scss) which is imported into the index.tsx

@import "~@ospreyfs/styles/functions;

Doing so gives me the following error

Error: Command failed with exit code 65: sass --stdin --load-path=/Users/dan.lincoln/Documents/local-dev/snowpack-demo/src/styles --load-path=/Users/dan.lincoln/Documents/local-dev/snowpack-demo --load-path=/Users/dan.lincoln/Documents/local-dev/snowpack-demo/node_modules
Error: Can't find stylesheet to import.
  ╷

It appears that snowpack doesn't look in node_modules and can't see the file, I was able to get around this by using '../../node_modules/@ospreyfs/styles' but this feels a little hacky and I'd much rather be able to import from node_modules into a scss file.
