Can't build using stack on OS X

[jwhitley]

[N.B.: this is quite possibly also relevant to commercialhaskell/stack than stackage-view, but I'm starting the discussion here.]

Repro steps

1. On an OS X box, install stack and clone this repo.
2. cd path/to/stackage-view
3. stack build

Actual results

>> stack build
Cannot find 'docker' in PATH.  Is Docker installed?

Expected results

stackage-view builds natively, so it can be invoked in a Cabal project directory.

Notes

The stack.yml file includes the stanza:

docker:
  repo: fpco/ghcjs-dev

This means that what should be a straightforward local build of this tool now must be built inside of a docker instance. This makes for a positively bizarre workflow, since the primary usage of this tool appears to be on a development host.

I fully understand the benefits of fully reproducible builds using docker (and VMs in general). Yet those benefits don't appear to apply to stackage-view because it's a client tool, not a server tool.

[jwhitley]

Ah ha! From this comment by @snoyberg it's now clear that the current stack.yaml setup is to satisfy this build's dependency on GHCJS, thus the repo: ghcjs-dev docker image.

The error reporting observed below is rather obscure for a missing CLI dependency:

@jwhitley could you build it finally ? I switched to the 3.XX listed her https://hub.docker.com/r/fpco/stack-ghcjs-build/tags/ to no avail (some permission in .profile popping up when stack build-ing ). retrying my luck with 2.16 (10Go... !)

$ stack build                                                                                                                                                      not sandboxed
tar: ./.profile: Cannot open: Permission denied
tar: ./.bashrc: Cannot open: Permission denied
tar: ./.bash_logout: Cannot open: Permission denied
tar: Exiting with failure status due to previous errors

with 2.16 as well. that's annoying. no idea where this come from..

Edit : same as here apparently
commercialhaskell/stack#488

cabal build as of now does not succeed either : I give up. that's my haskell experience when not using Nix or Stack. can't wait for the dev tooling to improve
