I've made a cabal sandbox, installed a package to it, yet runhaskell Setup configure complains that the package dependency that I just installed is missing.

I verified the package name and version and that's okay.
Running cabal install --dependencies-only says "all the requested packages are already installed".

What's going on & how can I fix it?

If relevant I've encountered this with QuickCheck-2.7.5 on Windows 7 with cabal-install 1.20.0.3 using cabal 1.20.0.1 and ghc 7.6.3.

Configuring through runhaskell Setup configure outputs:

Configuring MyPackage-0.1.0.0...
Setup.hs: At least the following dependencies are missing: QuickCheck ==2.7.5

  • What does `cabal configure` say ? – Sibi Jul 09 '14 at 14:56
  • you're running `Setup.hs` with `runhaskell`, have you tried just running `cabal build`? That'll do nothing but compile your project with your configuration in your `.cabal` file. IIRC `runhaskell` is just a wrapper around `ghc` and is agnostic of `cabal`. – bheklilr Jul 09 '14 at 15:01

    Instead of running `runhaskell Setup configure`, you should do `cabal configure`. `runhaskell` doesn't know about sandboxes. – user2407038 Jul 09 '14 at 15:08

    @user2407038 Solved my issue, thank you! Perhaps post it as an answer. – MasterMastic Jul 09 '14 at 15:30

Instead of running runhaskell Setup configure, you should do cabal configure. runhaskell doesn't know about sandboxes.
