Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: binary-0.8.6.0 (user goal)
[__1] next goal: ghc (user goal)
[__1] rejecting: ghc-8.6.1 (constraint from user target requires ==8.4.4)
[__1] rejecting: ghc-8.4.4/installed-8.4... (conflict: binary==0.8.6.0, ghc =>
binary==0.8.5.1/installed-0.8...)
[__1] rejecting: ghc-8.4.3, ghc-8.4.1, ghc-8.2.2, ghc-8.2.1 (constraint from
user target requires ==8.4.4)
[__1] fail (backjumping, conflict set: binary, ghc)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: binary, ghc
