Hi I am trying to install hakyll in a cabal sandbox, but somehow it doesn't work. Here's what I am doing:
$ cabal sandbox init $ cabal install hakyll Resolving dependencies... cabal: Could not resolve dependencies: trying: hakyll-4.8.3.2 (user goal) next goal: base (dependency of hakyll-4.8.3.2) rejecting: base-4.6.0.1/installed-8aa... (conflict: hakyll => base>=4.8 && <5) rejecting: base-4.9.0.0, 4.8.2.0, 4.8.1.0, 4.8.0.0, 4.7.0.2, 4.7.0.1, 4.7.0.0, 4.6.0.1, 4.6.0.0, 4.5.1.0, 4.5.0.0, 4.4.1.0, 4.4.0.0, 4.3.1.0, 4.3.0.0, 4.2.0.2, 4.2.0.1, 4.2.0.0, 4.1.0.0, 4.0.0.0, 3.0.3.2, 3.0.3.1 (global constraint requires installed instance) Backjump limit reached (change with --max-backjumps).
Note: when using a sandbox, all packages are required to have consistent dependencies. Try reinstalling/unregistering the offending packages or recreating the sandbox.
Then I tried (inside the sandbox):
$ cabal install cabal-install
which installed cabal 1.24.0.0 into the sandbox. Now, when I am using it, I am getting different errors:
$ .cabal-sandbox/bin/cabal install hakyll Warning: cannot determine version of /usr/lib/ghc/bin/haddock-ghc-7.6.3 : "" Resolving dependencies... cabal: Could not resolve dependencies: trying: parsec-3.1.11/installed-4f0...

Note: when using a sandbox, all packages are required to have consistent dependencies. Try reinstalling/unregistering the offending packages or recreating the sandbox.
What is going on here? Why am I getting different errors with the new cabal version? What is the relationship between system-wide packages and those in the sandbox? I thought sandbox is meant to be an isolated environment?!? How do I get the list of all the packages currently installed in the sandbox? Is this: $ ls ./lib/x86_64-linux-ghc-7.6.3/ async-2.1.0 ed25519-0.0.5.0 parsec-3.1.11 base16-bytestring-0.1.1.6 hackage-security-0.5.2.1 random-1.1 base64-bytestring-1.0.0.1 HTTP-4000.3.3 stm-2.4.4.1 bytestring-builder-0.10.8.1.0 mtl-2.2.1 tar-0.5.0.3 Cabal-1.24.0.0 network-2.6.3.1 transformers-0.5.2.0 cryptohash-sha256-0.11.100.1 network-uri-2.6.1.0 zlib-0.6.1.1 the way? Why is 'base' not on the list, although the new cabal is not complaining about it anymore? This is the latest Debian stable.
