#615: cabal install attempts to reinstall "same version" of already-installed package ---------------------------------+------------------------------------------ Reporter: guest | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: Linux | ---------------------------------+------------------------------------------ This is on ghc 6.12.1 rc2. The problem occurs because I installed a different version of ghc-syb than the one in hackage, but which retained the same version *number* as the one in hackage. Bumping up the version number of the alternate version, solved the problem, but it was confusing, and I believe I may have experienced this before without understanding what was happening. The alternate version of ghc-syb I used is at git://github.com/waern/ghc- syb.git I was working on scion to try and get it to build on ghc 6.12.1, and when I tried to cabal install it from my working directory, cabal install started to reinstall ghc-syb - even though ghc-syb was already installed, with the same version number as the version it was trying to reinstall. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/615 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
