Answer 1

控制器构造函数必须在数组中传递

app.controller('myCtrl', ['$scope', function($scope) { //your controller code here } ]);

Answer 2

该错误与应用程序的初始化方式和双 ng-app 有关。您可以通过手动引导 angularjs 轻松验证：

当您同时删除 ng-app 并在底部 controllers/controller.js 处添加以下代码段时，您的脚本有效：

angular.element(document).ready(function() { angular.bootstrap(document, ['myApp']); });
