Re: [Haskell-beginners] [web-devel] yesod dependency hell

Thomas, I tried what you suggested and I still have the exact same problem. On Wed, Jun 22, 2011 at 1:50 PM, Michael Litchard wrote:

My thinking is that this problem comes up anytime someone wants to play around with experimental code. As evidenced by the yesodwiki.cabal file, I think there's a more straightforward solution. I'm just not seeing it.

one idea: move .ghc and .cabal to temp directory.

start over with a clean slate.

Configuring Aframe-0.0.1... Warning: This package indirectly depends on multiple versions of the same package. This is highly likely to cause a compile failure. package yesod-auth-0.4.0.2 requires yesod-form-0.1.0.1 package yesod-0.8.2.1 requires yesod-form-0.1.0.1 package Aframe-0.0.1 requires yesod-form-0.2.0

I specified in Aframe.cabal yesod-form 0.2.0. The above warning is what I was looking to avoid. What is the solution to this problem? I could not find an obvious solution in yesodwiki.cabal, even though I see it's doing something similar to what I want. How did you deal with the above warning message?

Have a look at the yesodwiki[1]; basically, you can't use the yesod package itself, only the subpackages. This is by design so that a single Yesod release will keep API stability, while users can still experiment with newer versions of underlying packages.

I need to use yesod-form 0.2.0. The problem is that the yesod package, and the yesod-auth package expect yesod-form to be 0.1.0* I tried changing the .cabal files but that breaks in ways that makes me think the fix is not so simple. How do I go about being able to use yesod-form 0.2.0
