Re: [Haskell-beginners] Disappearing Module Problem

I was using "cabal install aeson" and "cabal install http-enumerator". Running the combined command fixed the issue. I'd forgotten that cabal allows for it. Is this necessary because of mutual dependencies? With the Platform installation of cabal, I could run cabal install for each package and everything would work fine. What's the difference?

I'm trying to install aeson and http-enumerator on an otherwise fresh installation of ghc 7.2 on OS X 10.7. I was inspired by beastaugh's gist on getting cabal-install running on Lion: https://gist.github.com/1169332. I can install either aeson or http-enumerator and it'll work fine. However, as soon as I install the second one the first one disappears. The files are all there in .cabal/lib, but ghc can't find the module. Any ideas?

What command are you using to install these, specifically?

What does the following do:

...

cabal install aeson http-enumerator

Thanks, Antoine
