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

I solved the problem.
thanks

how did you solve the problem? mine hasn’t been resolved

you have to install ghc 8.10.4 do not upgrade to version 9.1.0

This is also happening to me. Ive got GHC version 8.10.7 (as stated in coin cashew as a requirement)

Yes
