我正在其教程中尝试反应香蕉的示例。当我尝试将示例加载到ghci中时，出现错误。
Could not find module `Reactive.Banana.Frameworks.AddHandler'
运行它ghci -v会在底部给出输出。我安装wx-2.8了wxWidgets-0.13.1.3ubuntu 14.04 LTS。
当我查看我的 cabal 目录时，该AddHandler文件确实不存在：
$ 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
有人可以告诉我出了什么问题，我该如何解决这个错误？
谢谢，
