How do I fix missing @angular/Core modules?

I can not run the Angular 2 project.

What I tried: - running the project by using npm install and npm start | does not work - I cloned quickstart from the github and replaced with my src folder and I still get the "can not find module in @angular/core"

Here is the full console output: https://www.dropbox.com/s/5plmqrjd6ge0lta/error.txt?dl=0
