I have made my project using Angular-cli (https://github.com/angular/angular-cli) and I tried to follow https://github.com/samvloeberghs/protractor-gherkin-cucumberjs-angular2.

do i need to do some extra step that protractor will compile the typescript files first? or is there anything i am missing?

Update typescript to 2.0+ and protractor 4.0+ . Make sure you update your global and local version. Updating typescript to 2.0 should fix it.

The main problem is this:

Cannot find namespace 'protractor'

You need to fix that. You either need to define protractor typings globally or

import {protractor} from 'protractor'

I don't know your tsconfig.js or system.config.js but you essentially have to enable the above to have tsc resolve protractor module.
