Re: [Haskell-cafe] Yesod devel issue: cannot satisfy -package-key main

I've had rebuild `yesod-bin` using same snapshot as in project, which was selected as 6.27. Otherwise `yesod devel` reported an error about compiler version mismatch. But default compiler is GHC 8, you're right. I was able to resolve this doing `stack install --resolver=6.27` using sources from Git HEAD and removing `yesod` binary already installed in ~/.stack/snapshots/<arch>/lts-6.27/7.10.3/bin. Thanks.
