javascript - WARNING: Tried to load angular more than once. Angular JS

I am trying to view my app after running Grunt Build. I use grunt serve:dist to see all production ready build but in the browser I get an infinite loop saying:

WARNING: Tried to load angular more than once.

I have read this occurs because the TemplateURL: may be wrong after concatenation. As in this post: Tried to Load Angular More Than Once

But how do I fix this? Here is my app.js

/* global libjsapp:true */


'use strict';

var libjsapp = angular.module('libjsApp', [
  'ngCookies',
  'ngResource',
  'ngSanitize',
  'ngRoute'
]);

libjsapp.config(['$routeProvider', function ($routeProvider, $locationProvider) {
    $routeProvider
      .when('/', {
        templateUrl: 'views/posts.html',
        controller: 'PostsCtrl'
      })
      .otherwise({
        redirectTo: '/'
      });
  }]);

In my case this was due to the following html code:

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <title>Testapp</title>
</head>

<body ng-app="testApp">

  <main ui-view>

  <script src="bower_components/jquery/jquery.js"></script>
  <script src="bower_components/angular/angular.js"></script>
  <script src="bower_components/angular-ui-router/release/angular-ui-router.js"></script>

  <script src="scripts/main.js"></script>
</body>

</html>

As you can see, the <main> is not closed. This led to my variant of 'WARNING: Tried to load angular more than once.' issue.
