Upgrading Angular version - angularjs

Question

I have a web application using angular v1.1.5 and i am trying to update this to v.1.2.9.
I have downloaded v1.2.9 and the corresponding route.js file however when trying to run my application, i am seeing the below:
Error: [$injector:modulerr] http://errors.angularjs.org/1.2.9/$injector/modulerr?p0=app&p1=%5B%24injector%3Amodulerr%5D%20http%3A%2F%2Ferrors.angularjs.org%2F1.2.9%2F%24injector%2Fmodulerr%3Fp0%3DngRoute%26p1
main.js:
(function(require) {
'use strict';
require.config({
baseUrl: '/resources/js',
paths: {
'zepto' : 'vendor/zepto',
'jquery' : 'vendor/jquery',
'angular' : 'vendor/angular',
'ngRoute' : 'vendor/route',
// 'ngResource': 'vendor/resource',
'router' : 'vendor/page',
'history' : 'vendor/history.iegte8',
'event' : 'vendor/eventemitter2'
},
shim: {
'zepto' : { exports: '$' },
'angular' : { deps: ['jquery'], exports: 'angular' },
'ngRoute' : { deps: ['angular'], exports: 'angular' },
// 'ngResource': { deps: ['angular'], exports: 'angular' },
'app' : { deps: ['angular'] },
'router' : { exports: 'page'}
}
});
require(['angular', 'app'], function (angular, app) {
angular.bootstrap(document,['app']);
});
})(this.require);
app.js:
define("app", ["angular"], function(angular){
var app = angular.module("app", ['ngRoute']);
app.config(function($routeProvider, $locationProvider){
$routeProvider
.when("/home", {
templateUrl: "home.html",
controller: "HomeController"
})
.when("/products", {
templateUrl: "products.html",
controller: "ProductsController"
})
.otherwise({ redirectTo: '/products'});
});
return app;
});
Any advice appreciated.
Update**********************************************
If i change (app.js):
define("app", ["angular"], function(angular){
to:
define("app", ["angular", "ngRoute"], function(angular){
I get the following error:
TypeError: e is undefined
...controller,f),b.controllerAs&&(a[b.controllerAs]=f),c.data("$ngControllerControl...

I'm not familiar with require.js, but wouldn't you need to inject it here as well?
require(['angular', 'ngRoute', 'app'], function (angular, app, ngRoute) {
angular.bootstrap(document,['app', 'ngRoute']);
});
I might be out on deep waters here though.
