I am trying to install yesod, But it fails and one of the failures is to install http-conduit. So I tried to install that, and it fails, with this message: Building http-conduit-1.6.1.1... Preprocessing library http-conduit-1.6.1.1... <command line>: cannot satisfy -package-id asn1-data-0.7.1-25c9f2b3799c26151af97c0d9c79754c: asn1-data-0.7.1-25c9f2b3799c26151af97c0d9c79754c is unusable due to missing or recursive dependencies: base-4.5.0.0-597748f6f53a7442bcae283373264bb6 bytestring-0.9.2.1-df82064cddbf74693df4e042927e015e cereal-0.3.5.2-b01d76d961ef4facbe3e52a7b6ccef63 mtl-2.1.1-87121149c5eb4fc03f06f5894ea4ac0c text-0.11.2.0-b2986f5478f0efa626f8ba0494ed9670 (use -v for more information) Failed to install http-conduit-1.6.1.1 cabal.exe: Error: some packages failed to install: http-conduit-1.6.1.1 failed during the building phase. The exception was: ExitFailure 1 Any hints? I find that with each usage of cabal-install, my success rate and appreciation for it falls! :-) Each time it fails, and says to -force-reinstalls, that breaks more, etc... Not sure how to break out of this maze of "twisty turny passages that all look alike"..
