This is React JS, I just added Props-Types in my project, after that npm can't start this

 burgerapp@0.1.0 start C:\Users\ajeet\Desktop\burgerapp
> node scripts/start.js

    throw err;

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

In my experience, this just sometimes happens with npm when adding packages, especially with create-react-app projects. Delete node_modules and run npm install again, that should fix it
