@angular2-material/checkbox package is no longer been used since September of 2016. I found following message when i was trying to browse the material checkbox package in NPM site:

This package was used early in the pre-release development cycle of Angular Material v2, but has no longer been used since September of 2016. Development of Angular Material now occurs under scoped npm package @angular/material. Visit https://material.angular.io for the latest information and instructions for using Angular Material or check out the latest source code from https://github.com/angular/material2.

Already i have run following command but still not fixed: npm install --save @angular/material

That’s because your code still references the old package. If I get bored, I might fork this and update to latest angular and dependencies
