Error @types/core-js at compiling, npm start

I want to use https://github.com/videogular/videogular2 component in my app, and it needs @types/core. When i exec npm start at compiling it crashes, giving this errors:

I solved this by changing the electron:tsc script to:

"electron:tsc": "tsc --typeRoots [\"node_modules/@types\"] main.ts"

Have a look at the latest package.json: It now uses the -p flag of tsc which allows using a tsconfig.json. Works pretty well for me.
