현재 Haskell 플랫폼 2012.2.0.0, which says it uses base-4.5.0.0 및 base-4.5.0.0 includes the GHC.TypeLits module을 설치했습니다. 내가 GHC.TypeLits를로드 할 때GHC.TypeLits 모듈을로드 할 수 없습니다.
그러나, ghc은 그것을 찾을 수 없습니다 :

그래서 무슨 일이야? 현재의 Haskell 플랫폼에서 GHC.TypeLits을 사용할 수 있다고 가정하는 것이 잘못 되었습니까? 아니면 내가 사용할 수 있도록 필요한 단계를 건너 뛰고 있습니까?
