app.js
var myApp = angular.module('myApp',[]);
myApp.controller('mainCtrl',function($scope){
$scope.name="vignesh";
});I'm doing a basic app building with MEAN Stack, for most of the parts we use Node API's to connect with MongoDB and user authentication,I'm done with my authentication part in Node.js but while designing routing UI I'm facing this issue

Uncaught SyntaxError: Unexpected token

答案 0 :(得分：3)
您需要正确初始化app模块。
var myApp = angular.module('myApp', []);
<强>更新
由于每个JS文件都有不同的模块，因此您需要在使用该模块的任何提供者/服务时将它们组合在一起。在您的情况下，您使用了Auth服务，但authService模块没有注入。
<强> Controllers.js
angular.module('mainCtrl', ['authService']) //injected authService module
.controller('MainController', function($rootScope,$location,Auth){
<强> App.js
var myApp = angular.module('myApp',['mainCtrl']);
myApp.controller('mainCtrl',function($scope){
