Adding comment from @mdmower-csnw in the source issue (#110)

The updates to package-lock.json look complete (matches list of optionalDependencies for sass-embedded) and I verified I can compile successfully on both Windows 11 64bit and Debian 12 64bit.

Thanks Charlie! I can now install and run npm run init without errors on win11 x64.

Thanks for the quick fix on this @mahoneycm. I was not able to replicate the original issue on my Mac, but I went ahead and performed the test here to confirm that the update in this branch didn't create any new issues for me. It didn't! I was able to run npm run init on this branch without error.
