在反應香蕉中找不到AddHandler

Question

我正在嘗試在its tutorial中反應香蕉的實例。當我嘗試將示例加載到ghci時，出現錯誤。

Could not find module `Reactive.Banana.Frameworks.AddHandler' 

運行它與ghci -v給出底部的輸出。我在ubuntu 14.04 LTS上安裝了wx-2.8和wxWidgets-0.13.1.3。

當我看着我的陰謀目錄，AddHandler文件確實不存在：

$ ls lib/reactive-banana-0.8.0.0/ghc-7.6.3/Reactive/Banana/ 
Combinators.hi Frameworks.hi Model.hi Prim.hi Types.hi 
Experimental Internal  Prim  Switch.hi 

有人能告訴我是什麼地方出了錯，以及如何修正這個錯誤嗎？

感謝，

Answer 1

我已經通過該教程工作，並寫了一fixed version of the example:希望有所幫助。

Answer 2

刪除import Reactive.Banana.Frameworks.AddHandler一行。我認爲它已經轉移到其他地方，並且不需要明確的導入。
