Hi,
It seems to be saying that the package is incompatible with ghc 8.4. You
can try 'cabal install hsdev --allow-newer' but this probably well result
in a compile error if the package depends on ghc api.
If it does then you need an older platform.
Kind regards,
Tamar

Hi cafe,
I installed haskell platform for windows 10 and then ran `cabal install hsdev` I got the following error:
Resolving dependencies... cabal: Could not resolve dependencies: [__0] trying: hsdev-0.3.1.4 (user goal) [__1] trying: hlint-2.1.10 (dependency of hsdev) [__2] trying: haskell-src-exts-1.20.2 (dependency of hsdev) [__3] next goal: ghc-syb-utils (dependency of hsdev) [__3] rejecting: ghc-syb-utils-0.3.0.0 (conflict: hsdev => ghc-syb-utils>=0.2.3 && <0.3) [__3] trying: ghc-syb-utils-0.2.3.3 [__4] next goal: ghc (dependency of hsdev) [__4] rejecting: ghc-8.4.3/installed-8.4..., ghc-8.4.3, ghc-8.4.1 (conflict: ghc-syb-utils => ghc>=7.0 && <8.4) [__4] rejecting: ghc-8.2.2, ghc-8.2.1 (conflict: hsdev => ghc==8.4.*) After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: hsdev, haskell-src-exts, ghc-mod, hlint, base, ghc, ghc-syb-utils
Any Ideas on how to solve this? I'm clueless
