npm not starting

[Scottoca]

Hey guys, I'm fairly new to using terminal in general. I'm trying to set up an angular 2 environment for development but I keep getting these errors when I run 'npm start'

Can anyone help please?

iMac13:quickstart imac13$ npm start

angular-quickstart@1.0.0 prestart /Users/Admin/quickstart
npm run build

angular-quickstart@1.0.0 build /Users/Admin/quickstart
tsc -p src/

This has nothing to do with this module.
