Update: if i use GHC compiler v.8.10.2 (or hight), cabal configure --with-compiler=ghc-8.10.2 i get Error: cabal: Could not resolve dependencies: [__0] trying: Win32-network-0.1.0.0 (user goal) [__1] next goal: base (dependency of Win32-network) [__1] rejecting: base-4.14.1.0/installed-4.14.1.0 (conflict: Win32-network => base>=4.5 && <4.13) [__1] rejecting: base-4.12.0.0, base-4.11.1.0, base-4.11.0.0, base-4.10.1.0, 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) [__1] fail (backjumping, conflict set: Win32-network, base) After searching the rest of the dependency tree exhaustively, these were the goals I’ve had most trouble fulfilling: base, Win32-network if i use GHC compiler v.8.6.5, cabal configure --with-compiler=ghc-8.6.5 all is okey, but i get Error in original post
