homeController.js

app.controller('homeController', function ($scope, $http) {
    $scope.message = 'Everyone come and look!';
});

sidebarController.js

app.controller('sidebarController', function ($scope, $location) {
    $scope.isActive = function (viewLocation) {
        return viewLocation === $location.path();
    };
});

有人知道是什么导致了这个错误吗？新的角度和文件/过去的问题没有太大帮助。

为每个控制器注入依赖项。

1）

app.controller('homeController', ['$scope','$http',function ($scope, $http) {
    $scope.message = 'Everyone come and look!';
}]);

和

app.controller('sidebarController',['$scope','$location',function ($scope, $location) {
    $scope.isActive = function (viewLocation) {
       return viewLocation === $location.path();
    };
}]);

2）

app.controller('homeController',homeController); 
homeController.$inject = ['$scope','$http'];
function homeController($scope, $http) {
    $scope.message = 'Everyone come and look!';
}]);

和

app.controller('sidebarController',sidebarController);
sidebarController.$inject = ['$scope','$location'];
function sidebarController($scope, $location) {
    $scope.isActive = function (viewLocation) {
       return viewLocation === $location.path();
    };
}]);
