stack install codex fails with lts-7.0

[mayeranalytics]

Steps to reproduce

Starting with a clean Ubuntu VM:

1. stack --resolver lts-7.0 setup
2. stack --resolver lts-7.0 install codex

Result:

Run from outside a project, using implicit global project config
Using resolver: lts-7.0 specified on command line

While constructing the build plan, the following exceptions were encountered:

In the dependencies for codex-0.5.0.1:
    machines-directory must match >=0.0.0.2 && <0.3, but the stack configuration has no specified version
                       (latest applicable is 0.2.0.9)

Recommended action: try adding the following to your extra-deps in /home/parallels/.stack/global-project/stack.yaml:
- machines-directory-0.2.0.9

You may also want to try the 'stack solver' command
Plan construction failed.

Following the recommended action I add to the extra-deps in stack.yaml. After running stack --resolver lts-7.0 install codex again I get failure with recommendation to add machines-io-0.2.0.13.

The file .stack/global-project/stack.yaml then reads:

flags: {}
extra-package-dbs: []
packages: []
extra-deps:
  - machines-directory-0.2.0.9
  - machines-io-0.2.0.13

resolver: lts-7.0

Running stack --resolver lts-7.0 install codex again results in an error:

    setup-Simple-Cabal-1.24.0.0-ghc-8.0.1: Encountered missing dependencies:
    codex ==0.5.0.0

Doing the same with lts-6.12 works fine. Apparently there is a circular dependency somewhere.

Can you create a dependency graph with stack dot?

[mayeranalytics]

In the global stack project it's not possible to create a dependency graph with stack dot, it seems.

This may well be a problem created by codex. In any case it would be good if stack offered some insights into what's going on here. Right now I'm completely clueless.

[sjakobi]

Yeah, there's an issue with codex-0.5.0.1. See aloiscochard/codex#63 (comment).

Leaving this open for now in case someone wants to propose a UI improvement.
