Hi
I am trying to install hakyll in a cabal sandbox, but somehow it doesn't
work. Here's what I am doing:

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:

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.
Thanks!

Hi Stanislaw,

No idea. Perhaps remove the sandbox for the hakyll build and start a new
one.

Some packages are fixed with the GHC version, like the base one.

Yes.

The last hakyll version supporting your ghc compiler 7.6.3 was 4.7.5.2.
I don't know why cabal gets stuck here, it should take this hakyll
version, but you might help cabal with its dependency resolution by
directly installing 4.7.5.2:
cabal install hakyll-4.7.5.2
Greetings,
Daniel

Wait, have you installed 'cabal-install' into the same sandbox as
hakyll? That might cause the issues. Use a separate sandbox for hakyll.

I'd recommend trying out an installation using the Stack build tool
instead. Instructions on installing are available at:
https://haskell-lang.org/get-started
Once installed, you should be able to install hakyll with:
stack install hakyll --install-ghc
You'll get a message about the directory the executable is installed into,
which should be
~/.local/bin
