Unmet Peer Dependency Installation error

[demisx]

Trying to install the latest version, I get the following error:

$ git clone [email protected]:ui-router/quickstart-ng2.git
$ cd quickstart-ng2/
$ npm install
---
npm WARN @angular/[email protected] requires a peer of zone.js@^0.7.2 but none was installed.
npm WARN [email protected] requires a peer of @angular/router@^3.3.1 but none was installed.

To solve, update the mentionned dependencies, as the current release of the repo specifies older versions of those deps.
