Окружающая среда Haskell после переустановки

Окружающая среда Haskell после переустановки

Я недавно переустанавливал свою среду на Haskell, так как считал, что восстановил ее после восстановления после обновления Mac OS X до Mavericks.

Теперь каждый раз, когда я бегу cabal install cabal-installЯ получаю следующую ошибку.

После поисков, я нашел это: http://www.haskell.org/platform/ghc-clang-wrapper

Который я запускал, чтобы обернуть Clang для Haskell, однако вышеупомянутая ошибка все еще происходит

Бег ghc-pkg check

The following packages are broken, either because they have a problem
listed above, or because they depend on a broken package.
Cabal-1.18.1.3

Почему моя среда Haskell так феноменально нарушена? И как я могу это исправить?

Одним из подходов является удаление вашего местного ghc кеш пакета:

$ cd  ~/.ghc/  &&  rm -rf  */package.conf.d
$ ghc-pkg --user recache

После этого попробуйте cabal команда снова.

$ cabal install package-name

Это должно работать. Если это не так, попробуйте удалить cabal пакеты, затем повторить вышеуказанные шаги:

$ rm -rf  ~/.cabal

Если у вас все еще возникают проблемы, пропавший пакет может быть указан системным кэшем пакета ghc. Запустите эту команду:

$ ghc-pkg --user recache
$ sudo ghc-pkg recache
$ ghc-pkg -v check

Последняя команда должна напечатать системный кеш. На моей системе GNU/Linux он печатает это:

using cache: /home/sudoman/.ghc/x86_64-linux-7.6.3/package.conf.d/package.cache
using cache: /var/lib/ghc/package.conf.d/package.cache

На данный момент у меня нет для вас решения, основанного на опыте, но вы можете подумать об удалении кэша системных пакетов ghc, как описано выше, а затем выполнить повторное кэширование; или переустановить ghc/haskell-platform.

Проблема связана с тем, что cabal может отслеживать несколько версий одного и того же пакета.

Бег:

cabal install --reinstall Cabal-1.18.1.3

решает проблему
