我最近將一個應用程序從早期的Ionic 2 Alpha版本升級到了最新的Ionic 2 Beta 10.它已經導致我的一些代碼被破壞,並且我有一段糟糕的時間來理解錯誤,來自JavaScript控制檯。所有的TypeScript都捆綁到這個app.bundle.js文件中,這導致控制檯在識別錯誤時指向錯誤的代碼區域。理想情況下,我會在控制檯輸出中看到導致錯誤的實際文件。Ionic 2 - 如何理解app.bundle.js錯誤?
有誰知道我該如何做到這一點?
謝謝!

消息'沒有提供ConfigService! (ESOService - > ConfigService)'非常簡單:你使用'ConfigService'而不將它添加到任何組件的providers數組中。看看你在哪裏使用它,並將它添加到必須使用它的最頂層組件的'providers'數組中。 – sebaferreras
