我在添加 angular-route.js 时收到 ngRoute not found 的错误，我不明白为什么会这样
<!DOCTYPE html>
<html ng-app="Userapp">
<head>
<title>Alltotal</title>
<link rel="stylesheet" href="css/bootstrap.min.css">
<script src="js/lib/angular.js"></script>
<scipt src="js/lib/angular-route.js"></scipt>
<script src="js/app.js"></script>
<script src="js/controller/register.js"></script>
<script src="js/controller/show.js"></script>
</head>
<body>
<div class="container">
<div class="row">
<!--navigation-->
<div class="col-lg-12">
<ul class="nav nav-tabs">
<li role="presentation" class="active"><a href="#">Register</a></li>
<li role="presentation"><a href="#">Show users</a></li>
</ul>
</div>
</div>
<!--view-->
<div class="row">
<div class="col-lg-12">
<div ng-view></div>
</div>
</div>
</div>
</body>
</html>
我的 javascipt 是我认为它是完全正确的，但在运行时不起作用
var app = angular.module("Userapp", ['ngRoute']);
app.config(function ($routeProvider) {
$routeProvider.when('/', {templateUrl : 'partials/form.html',
controller: 'formctrl'});
});
