我开始从现有的 Angular 1 代码库派生一个新项目，目的是使用 ngUpgrade 使用 Angular 2 进行新开发。我已成功将 Angular 2 添加到项目中，但是当我尝试按顺序实例化 ngUpgrade引导应用程序的 ng2 端，我收到以下错误：

zone.js:461 Unhandled Promise rejection: Error: [$injector:modulerr] Failed to instantiate module NG2_UPGRADE_0_ due to:
  Error: [$injector:unpr] Unknown provider: $$testabilityProvider

我搜索了有关Failed to instantiate module NG2_UPGRADE_0_和的信息$$testabilityProvider，但找不到任何有用的信息。

这是一个相当复杂的项目，因此尝试将其分解为可行的 plunkr 具有挑战性。在我尝试这样做之前，是否有人对此有任何想法？

虽然我不确定，但这似乎与 Angular 1 版本有关。此错误在升级到 1.5.x 后消失。
