无法实例化app模块。为什么？

当我尝试加载包含AngularJS代码的html页面时，我在Firefox开发者控制台中收到以下错误：

Error: [$injector:modulerr] Failed to instantiate module bookApp due to:
[$injector:nomod] Module 'bookApp' 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.

请注意，当我单击index.html中的按钮时，Firefox开发人员控制台中没有输出，因为该模块尚未实例化。 如何解决此错误？

以下是index.html：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Find Book By ISBN</title>
<script type="text/javascript" src="bookController.js"></script>
</head>
<body ng-app="bookApp">

<div ng-controller="bookController">  
    <table>
        <tr>
            <td width=200>
                ISBN:<input type="text" ng-model="book.isbn" />
                <br>
                <button ng-click="findBook()">Find Book</button>
            </td>
            <td>
                ISBN: <span ng-bind="book.isbn"></span>
                <br/>
                Title: <span ng-bind="book.title"></span>
                <br/>
                Author: <span ng-bind="book.author"></span>
            </td>
        </tr>
    </table>
</div>

    <!-- build:js({app,.tmp}) scripts/main.js -->
    <script src="js/lib/angular.js"></script>
    <script src="js/lib/angular-resource.js"></script>
    <script src="js/lib/angular-ui-router.js"></script>
    <script src="js/lib/angular-ui-router-statehelper.js"></script>
    <script src="js/lib/angular-animate.js"></script>
    <script src="js/lib/angular-cookies.js"></script>
    <script src="js/lib/angular-storage.js"></script>
</body>
</html>

以下是bookController.js，与index.html位于同一目录中：

// create angular app
var bookApp = angular.module('bookApp', []);

// create angular controller
bookApp.controller('bookController', ['$scope', '$http', 'context', function($scope, $http,context) {  
    var bookId = 1;

    $scope.findBook = function() {
        console.log('test')
        $http.get(context + '/api/findbook/' + bookId).then(function(response) {          
            $scope.book = response.data;
        });
    };

}]);

这是来自Firefox控制台的完整堆栈跟踪：

您的bookController.js文件未包含在内，因此您只需在所有角度脚本标记后链接<script type="text/javascript" src="bookController.js"></script>。

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Find Book By ISBN</title>
</head>
<body ng-app="bookApp">

<div ng-controller="bookController">  
    <table>
        <tr>
            <td width=200>
                ISBN:<input type="text" ng-model="book.isbn" />
                <br>
                <button ng-click="findBook()">Find Book</button>
            </td>
            <td>
                ISBN: <span ng-bind="book.isbn"></span>
                <br/>
                Title: <span ng-bind="book.title"></span>
                <br/>
                Author: <span ng-bind="book.author"></span>
            </td>
        </tr>
    </table>
</div>

    <script src="js/lib/angular.js"></script>
    <script src="js/lib/angular-resource.js"></script>
