Hello, I am trying to use binary-serialise-cbor in my project. Since it's not on hackage I followed the docs and added the following to stack.yaml: packages: - '.' - location: git: https://github.com/well-typed/binary-serialise-cbor.git commit: 1e11ea5cc7810d241b2fe1bca0ed435baa4d4371 extra-dep: true flags: binary-serialise-cbor: newtime15: true And in my .cabal file I have: build-depends: base >= 4.7 && < 5, network-simple, time, binary-serialize-cbor, bytestring When I do stack build the package is downloaded and built but then I get the following error: Error: While constructing the build plan, the following exceptions were encountered: In the dependencies for hcopia-0.1.0.0: binary-serialize-cbor must match -any, but the stack configuration has no specified version I attached both files just in case. Regards, Juan
