Kann c2hs und Sprache-c nicht installieren

Question

Ich verwende Cabal hier, um Paket c2hs zu installieren. Allerdings erfordert es Glück, also habe ich happy mit cabal install happy installiert.

Nach, wenn Sie versuchen, c2hs und language-c zu installieren, bekomme ich package happy not found auf beide.

Hier ist das Terminal Protokoll:

~> cabal install happy

Ich musste ~/.cabal/bin zu meinem Pfad hinzufügen, und dann hat es funktioniert.
