Hi.
I´m trying to install ghc-mod from cabal on Win10 64Bit but I get this error
PS C:\Users\LeonWin10> cabal install ghc-mod Resolving dependencies... cabal.exe: Could not resolve dependencies: trying: ghc-mod-5.8.0.0 (user goal) next goal: base (dependency of ghc-mod-5.8.0.0) rejecting: base-4.10.0.0/installed-4.1... (conflict: ghc-mod => base<4.10 && >=4.6.0.1) rejecting: base-4.10.0.0, base-4.9.1.0, base-4.9.0.0, base-4.8.2.0, base-4.8.1.0, base-4.8.0.0, base-4.7.0.2, base-4.7.0.1, base-4.7.0.0, base-4.6.0.1, base-4.6.0.0, base-4.5.1.0, base-4.5.0.0, base-4.4.1.0, base-4.4.0.0, base-4.3.1.0, base-4.3.0.0, base-4.2.0.2, base-4.2.0.1, base-4.2.0.0, base-4.1.0.0, base-4.0.0.0, base-3.0.3.2, base-3.0.3.1 (constraint from non-upgradeable package requires installed instance) After searching the rest of the dependency tree exhaustively, these were the goals I've had most trouble fulfilling: base, ghc-mod, syb
It would be great, if someone has a solution :)
solved it by using stack. Please close this
Looks like you have GHC 8.2. ghc-mod doesn't support it yet, hence the error. Stack is still on GHC 8.0 by default, so that works out.
Closing per your request.
