javascript - Angular.js-providerInjector 错误

Question

我在 Angular 提供程序方面遇到问题，收到此错误:

Row 2696: Error: Unknown provider: a

使用未缩小的 Angular v 1.06，第 2696 行:

providerInjector = createInternalInjector(providerCache, function() {
    throw Error("Unknown provider: " + path.join(' <- '));
}),

这是代码:

var myApp = angular.module('myApp', [], function ($interpolateProvider) {
    $interpolateProvider.startSymbol('{[{');
    $interpolateProvider.endSymbol('}]}');
});

myApp.directive('buttonsRadio', function() {      
[...]
});


myApp.controller('MainController', function MainController ($scope) {
[...]
})

有什么想法吗？

编辑:添加错误消息:

在运行 uglify 或任何其他 ofuscator/压缩算法之前，您应该运行 grunt 任务 ng-annotate ，它将依赖项添加为字符串作为可注入(inject)数组，这使您的代码更加清晰，因为可注入(inject)注释可以作为构建步骤自动添加，而不必手动编码。

myApp.controller('MainController', function MainController ($scope) {
[...]
})

变成:

myApp.controller('MainController', ['$scope', function MainController ($scope) {
[...]
}])

看看:https://github.com/olov/ng-annotate

更新: ng-min AngularJS Pre-minifier 已弃用 –> 使用 ng-annotate
