Build script fails on Windows

[gratrockstar]

The npm run build and npm run start commands fail on Windows, producing tons of errors. Here's an example, this error seems to be repeated for every scss file (here, ... is the path to the WP install):

ERROR in css/style
Module not found: Error: Can't resolve '.\assets\scss\_index.scss' in 'C:\...\wp-content\themes\wds-bt'
Did you mean './.\assets\scss\_index.scss'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.
