Installazione della Cabal mancano i moduli

Question

L'installazione di ghc non era aggiornata, quindi ho deciso di reinstallare ghc e cabal per risolvere eventualmente alcuni problemi. Ho iniziato seguendo i passaggi here. GHC ora è la versione 7.8.3.

Ho quindi rimosso ~/.cabal e ho provato a installare utilizzando i passaggi ma non riesce. Così ho rimosso .cabal di nuovo ed ho provato i passi here ma quando ho eseguito sh bootstrap.sh si corre in moduli mancanti:

Answer 1

È possibile utilizzare ghc-pkg unregister su ciascuno dei pacchetti rotti per pulirli correttamente, o Probabilmente soffiare via l'intera cartella ~/.ghc e ricominciare. Potrebbe essere necessario utilizzare --force per evitare di dover rispettare l'ordine di dipendenza dei pacchetti.

Answer 2

Hai rimosso ~/.ghc anche quando hai rimosso ~/.cabal? In caso contrario, ti suggerisco di provarlo, poiché se ho capito bene, il primo potrebbe contenere riferimenti a pacchetti installati nel secondo.
