Do you know how can I remove network-2.2.1.10 that is not needed because a higher version exists. Should I delete anything under ~/.ghc and ~/.cabal, and reinstall ghc and cabal-install, and those pacakges installed before using cabal? Thanks for your link of the Haskell-platform. I will wait for the official release and hope it will be soon. Christian Maeder writes:

What does "ghc-pkg list" and "ghc-pkg check" say?

Cabal-1.10.1.0, directory-1.1.0.0 and process-1.0.1.5 should be there after installation of GHC 7.0.2. (I've actually installed cabal-install-0.10.0 using an older cabal, but that does not work on macs and may not be the recommended way.)

I think I've used http://www.galois.com/~dons/code/2011.2.0.0/haskell-platform-2011.2.0.0.tar.... from http://www.galois.com/~dons/code/2011.2.0.0/, but they are not official yet.

Hi,

After I installed GHC 7.0.2 and cabal-install 0.10.0 using Cabal library 1.10.1, I found that some package failed to install. For example like Happy, I got the following error:

cabal install happy Resolving dependencies... <command line>: cannot satisfy -package Cabal-1.10.1.0: Cabal-1.10.1.0-64e8f05722ea5bbdf07df2e5a3491105 is unusable due to missing or recursive dependencies: directory-1.1.0.0-85d1d0f9d96dffdacf64f3cc6fba6f2f process-1.0.1.5-4cab1bf0666275ac101dd48c7565b64c (use -v for more information) cabal: Error: some packages failed to install: happy-1.18.6 failed during the configure step. The exception was: ExitFailure 1

Besides happy package, some other packages like ghc-mod, hmatrix also failed to install. Does anyone else have the same issue after installed ghc 7.0.2?

By the way, does anyone hear anything about Haskell-platform 2011.2 ?

Thanks!

Thank you! I fixed the broken package, network-2.2.1.10 by manually removing it locally and recache the ghc's package cache by running ghc-pkg recache. Thanks though for the unregister option. Now ghc-pkg check doesn't return any broken packages. But Cabal seems still got problem. I got the same cabal problem when I tried to test with the haskell-platform 2011-2. I have post another with that regard. -- View this message in context: http://haskell.1045720.n5.nabble.com/have-anyone-tried-GHC-7-0-2-tp3413510p3...
