Angular 未处理的承诺拒绝2 RC 5

将angular2升级到rc5后，尝试加载我的应用程序时出现以下错误：

您是否创建了app.module.ts？当你升级到rc-5时，你需要它。按照下面的说明操作

---

您配置依赖项注入/提供程序的方式似乎有问题。。。你能给我更多的提示吗？当错误发生时。谢谢看起来您忘记在组件或其rc5错误中添加服务作为提供商，angular没有看到它，请检查git上的开放问题。@ThierryTemplier发生在应用程序“Loading..”屏幕中，我不知道从哪里开始查找，因为此错误不涉及任何组件。您是否尝试添加模块@TommyF我是否需要将bootstrap（）方法更改为

platformBrowserDynamic（）.bootstrapModule（AppModule）和所有参数移动到
导入：[]
？
