angularjs – ocLazyload没有加载模块

<!-- inject:js -->
        <script src="/packages/libs/jquery/dist/jquery.js"></script>
        <script src="/packages/libs/angular/angular.js"></script>
        <script src="/packages/libs/oclazyload/dist/ocLazyLoad.js"></script>
        <script src="/packages/libs/angular-ui-router/release/angular-ui-router.js"></script>
        <!-- endinject -->

        <script src="app/app.js" ></script>
        <script src="app/common/app.config.js" charset="utf-8"></script>

我的app.js –

(function () {
    angular.module('app',['ui.router','oc.lazyload']);

    angular.element(document).ready(function () {
        angular.bootstrap(document,["app"]);
    });
})();

但由于某种原因,它根本不加载oc.lazyload模块.可能是什么问题？我错过了什么吗？

Uncaught Error: [$injector:modulerr] Failed to instantiate module app due to:
Error: [$injector:modulerr] Failed to instantiate module oc.lazyload due to:
Error: [$injector:nomod] Module 'oc.lazyload' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
