Angular2 EXCEPTION：没有e的提供者！ （e - > e）

所以我有一个非常简单的组件，它装载了一个简单的路由器 . 我正在使用所有基本的东西，如ngFor，ngSwitch，ngIf，我通过COMMON_DIRECTIVES注入它们

没有堆栈跟踪，我得到了这个非常模糊的错误，所以我真的没有't know what'继续 . 我在https://github.com/angular/angular/issues/6223看到了一些潜在相似的东西 .

例外：没有e的提供者！ （e - > e）STACKTRACE：错误：在t [作为构造函数]的DI异常（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js：6：5082）在t [作为构造函数]（ http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js：1：26551）at new t（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js：1： 270.）在e._throwOrNull（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js：9：5943）的e._getPrivateDependency（http：// localhost：5000 / node_modules / angular2 / bundles / angular.min.js：9：6605）在e._getByKey（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js：9：6397）e._getByKey（http：// localhost：在e._getByDependency（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js：9：5602）处，e / 5000，node_modules / angular2 / bundles / angular2.min.js：9：5826） . _instantiate（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min.js:9:3644）位于e._instantiateProvider（http：// localhost：5000 / node_modules / angular2 / bundles / angular2.min） .
