Hello,
after installing digestive-functors-blaze with:
cabal install digestive-functors-blaze
My prog doesn't compiles anymore:
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.
Followed by an error on MonadCatchIO.
I'm using the following versions:
happstack-server-0.5.0.2
mtl-1.1.0.2
blaze-html-0.2.3
web-routes-0.22.0
text-0.7.2.1
But cabal tried to install newer versions for these:
mtl-2.0.1.0
blaze-html-0.3.2.1
text-0.11.0.1
I already add this problem in the past, when I tried to update my MTL...
With absolutely no success!!
I encountered the same sort of problem of multiple versions dependencies. I
was unable to solve it.
After some research, I followed an advise telling that you should stick with
the same version of the libraries during development, so that I did: I went
back to the previous versions.
Is there a safe way to update some base libraries like MTL and all depending
libraries?
Would I be able to use digestive-functors with my current set of libraries?
Thanks,
Corentin
