Resolving dependencies…

cabal: Could not resolve dependencies:

[__0] trying: Win32-network-0.1.0.0 (user goal)

[__1] trying: base-4.15.0.0/installed-4.15.0.0 (dependency of Win32-network)

[__2] next goal: byron-spec-chain (user goal)

[__2] rejecting: byron-spec-chain-0.1.0.0 (conflict:

base==4.15.0.0/installed-4.15.0.0, byron-spec-chain => base>=4.11 && <4.15)

[__2] fail (backjumping, conflict set: base, byron-spec-chain)

After searching the rest of the dependency tree exhaustively, these were the

goals I’ve had most trouble fulfilling: base, Win32-network, byron-spec-chain
