ne peut pas construire projet Yessod en utilisant l'outil de pile de Haskell

Question

J'ai récemment essayé d'utiliser stack pour créer un projet Yessod, compte tenu de la quick start sur leur site web:

1. Suivez les instructions d'installation pour la pile pour obtenir pile .
2. Créer un nouveau site échafaudée: stack new my-project yesod-sqlite && cd my-project
3. installer l'outil de ligne de commande yessod: stack build yesod-bin cabal-install --install-ghc
4. bibliothèques Ancienneté: stack build
5. serveur Lancer devel: stack exec -- yesod devel
6. Voir votre site Yessod à http://localhost:3000/

Le problème que j'ai rencontré apparaît quand j'essaie de faire stack build yesod-bin cabal-install --install-ghc, il est dit:

<command line>: cannot satisfy -package Cabal-1.18.1.5 
(use -v for more information) 
Exit code ExitFailure 1 while running ["ghc","-clear-package-db","-global-package-db","-hide-all-packages","-package","base","-package","Cabal-1.18.1.5","/tmp/stack8413/Setup.hs","-o","/home/self/.stack/setup-exe-cache/x86_64-linux/tmp-setup-Simple-Cabal-1.18.1.5-ghc-7.10.3","-rtsopts"] in /tmp/stack8413/ 

Essayer avec le drapeau -v apporte cette beauté:

Quand je fais un ls sur le répertoire /home/self/.stack/setup-exe-cache/x86_64-linux/ il montre un dossier vide. Faire stack setup:

stack will use the GHC on your PATH 
For more information on paths, see 'stack path' and 'stack exec env' 
To use this GHC and packages outside of a project, consider using: 
stack ghc, stack ghci, stack runghc, or stack exec 

Mon env dev est essentiellement Lubuntu, avec GHC 7.10.3 et cabale 1.22.5.0. J'ai déjà essayé de réinstaller stack: P.

Mise à jour: je lance stack build yesod-bin cabal-install --install-ghc --no-system-ghc, et obtenez:

Running /home/self/.stack/programs/x86_64-linux/ghc-7.10.3/bin/ghc-pkg --user --no-user-package-db --package-db /home/self/.stack/snapshots/x86_64-linux/lts-6.9/7.10.3/pkgdb dump --expand-pkgroot exited with ExitFailure 1 
ghc-pkg: /home/self/.stack/snapshots/x86_64-linux/lts-6.9/7.10.3/pkgdb/package.cache: GHC.PackageDb.readPackageDb: inappropriate type (not a ghc-pkg db file, wrong file magic number) 

Answer 1

On dirait une mauvaise configuration de votre GHC global (celui installé via apt). Pouvez-vous essayer en cours d'exécution:

stack build yesod-bin cabal-install --install-ghc --no-system-ghc 

Si cela fonctionne, je vous recommande soit:

1. Retrait du système installé GHC
2. Modifier la configuration de votre Stack pour désactiver le système GHC (voir the docs)
