Re: [web-devel] Installing Yesod on OSX

I did that, I ran the command from the Yesod website: cabal install happy && cabal install alex && cabal install yesod On Sun, Apr 3, 2011 at 10:36 AM, Michael Snoyman wrote:

You probably need to install alex and happy. Cabal doesn't automatically install them, since they are executables used at compile time and not libraries. Try:

cabal install alex happy cabal install yesod

Let us know if you still have problems.
