ngUpgrade 中的未知提供程序错误(Angular 1/2 混合应用程序)

Unknown provider error in ngUpgrade (Angular 1/2 hybrid application)

我正在开始一个从现有 Angular 1 代码库派生出来的新项目,目的是使用 ngUpgrade 使用 Angular 2 进行新开发。我已成功添加 Angular 2 到项目,但是当我尝试实例化 ngUpgrade 以便 bootstrap 应用程序的 ng2 端时,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:

我搜索了有关 Failed to instantiate module NG2_UPGRADE_0_$$testabilityProvider 的信息,但没有找到任何有用的信息。

这是一个相当复杂的项目,因此试图将其分解为一个可行的 plunkr 是一项挑战。在我尝试这样做之前,有人对此有任何想法吗?

虽然我不确定,但这似乎与 Angular 1 版本有关。升级到 1.5.x 后这个错误消失了。
