Question

我开始从现有的Angular 1代码库派生出一个新项目，打算使用ngUpgrade使用Angular 2进行新的开发。我已成功将Angular 2添加到项目中，但是当我尝试实例化时ngUpgrade为了引导应用程序的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$$testabilityProvider的信息，但未找到任何有用的信息。

这是一个相当复杂的项目，因此试图将其拆分为可行的傻瓜是一项挑战。在我尝试这样做之前，这是否有人有任何想法？

Answer 1

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

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