Error "Unexpected token import" when trying to run Angular Universal

I am trying to produce an Angular Universal, but I came across an issue with "ts-node server.ts". Output logged below:

$ npm run start

> prestart public-site
> ng build --prod && ngc

If you have any idea how to fix this, it would be greatly appreciated.
