Getting error when run npm install

[shiva-p17]

Hi, I have downloaded the start - final - version branch and when I do the npm install command, I'm getting the following error,

npm ERR! 404 Not Found npm ERR! 404 npm ERR! 404 'angular/router-deprecated' is not in the npm registry. npm ERR! 404 You should bug the author to publish it npm ERR! 404 It was specified as a dependency of 'angular2-quickstart' npm ERR! 404 npm ERR! 404 Note that you can also install from a npm ERR! 404 tarball, folder, or http url, or git url.

Am I missing anything?

Thanks for the help.
