I have project angular-cli
~root~/src/typings.json
{ \"globalDevDependencies\": { \"angular-protractor\": \"registry:dt/angula
A bit of a late response but I had a similar issue using Angular CLI RC.0.
It turned out that I hadn't install and imported the typings, which can be done as follows:
npm install --save-dev @types/googlemaps import {} from '@types/googlemaps';
