Ambiguous module name

23:37

別にddump-splicesに限ったわけではないですが。

ghc -ddump-splices Model.hs
~/Documents/OsojiPhoto/OsojiPhoto $ ghc -ddump-splices Model.hs
GooglePlusOAuth.hs:42:8:
    Ambiguous module name `Data.Aeson.Types':
      it was found in multiple packages:
      aeson-0.5.0.0 aeson-native-0.3.3.2

こんなときは

ghc -hide-package aeson-native -ddump-splices Model.hs
