Elm-test - how to fix package dependency errors?

Hi,

I have also run into this problem before - here is how you can diagnose it.

elm-test creates another elm.json to build and run the test cases. This can be found under:

elm-stuff/generated-code/elm-explorations/test/elm.json

Paste the contents of that file into this:

https://www.markuslaire.com/github/elm-dependencies-analyzer/

and it will tell you which dependencies are not compatible and why. In your case it says:

Selected versions have dependency conflicts:

* elm/json 1.0.0
  * 1.1.0 <= v < 2.0.0 needed by elm/http 2.0.0

Somehow elm-test has replaced your indirect elm/json/1.1.3 with a direct elm/json/1.0.0.

To fix it I ran:

> elm install elm/json

which simply moved that dependency from indirect into direct.

Worth raising an issue against elm-test for this one (I did it for you): https://github.com/elm-explorations/test/issues/103
