How do I uninstall older versions of GHC?

I installed Haskell Platform 7.10.3 on my mac and when it finished it said that it had detected older versions of GHC and to uninstall them, but how do I do that?

I'm using a macbook air with OS X 10.11.3.

Solution

  • You can uninstall prior platforms by running

    uninstall-hs from the command line.

    You'll get an output like:

    -- Versions found on this system
7.10.3
-- To remove a version and all earlier: uninstall-hs thru VERSION
-- To remove only a single version:     uninstall-hs only VERSION

    And you can proceed from there...
