I believe this might be due to the fact that each package contains the full path to the location when it was first created. Look into. .ghc/YOUR_PLATFORM/package.conf.d
(for me, it's .ghc/x86_64-darwin-7.6.3/package.conf.d
). You'll see a lot of .conf
files, and each will contain hardcoded paths:
[...]
import-dirs: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/lib
library-dirs: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/lib
[...]
haddock-interfaces: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/doc/html/pandoc-types.haddock
haddock-html: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/doc/html
You can either manually update the files for the contents to point to the right location or write a script which would do it for you.
Then you need to update the package.cache files (might require a sudo here and there):
pejvan$ ghc-pkg recache
pejvan$ ghc-pkg recache --user
Finally, check that everything is now fine:
pejvan$ ghc-pkg check
