Package Manager stops working, says something about packages too old.
And if I tried to update Cabal package index by `cable update`, then I getting the error below:
/usr/local/lib/HaskellCLI.0.2-9.6-2/bin/cabal update
Downloading the latest package list from stackage-lts-9.6
cabal: Failed to download http://www.stackage.org/lts-9.6/00-index.tar.gz :
HTTP code 308.
I think this caused by that Cabal didn't follow the HTTP redirect.
You are right, this is due to Cabal not following the redirect. It is a shortcoming in the version of Cabal that ships with Haskell for Mac and doesn't properly deal with a recent change in the set up of the Stackage package repository. I am working on a new version of Haskell for Mac that, among other things, fixes the issue. In the meantime, could you please manually change the Cabal configuration as follows:
* Edit the file "~/Library/Containers/com.haskellformac.Haskell.basic/Data/Library/Application\ Support/Cabal/cabal.config"
* Replace the second line with the following text "remote-repo: stackage-lts-9.6:http://hackage.fpcomplete.com/`". (It is just the URL that actually changes.)
This should fix the problem for now.
I am sorry about the inconvenience,
Manuel
Works like charm. :)
