Failed to instantiate module [$injector:unpr] Unknown provider: $routeProvider

I received this error upon upgrading from AngularJS 1.0.7 to 1.2.0rc1.

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

In my case it was because the file was minified with wrong scope. Use Array!

app.controller('StoreController', ['$http', function($http) {
    ...
}]);

Coffee syntax:

app.controller 'StoreController', Array '$http', ($http) ->
  ...
