utils.getElmVersion returns empty version

Expected Behavior

Extension should work (look for Elm packages in right directory) utils.getElmVersion should return Elm version that is installed. 0.19.1 in this case.

Current Behavior

UPDATED: Found that utils.getElmVersion is returning empty value instead of version.

---

Opening the elm-spa-example project. The only thing that seems to work is syntax highlighting. One of the first errors in output is Error: ENOENT: no such file or directory, open 'C:\Users\janis\AppData\Roaming\elm\packages\NoRedInk\elm-json-decode-pipeline\1.0.0\elm.json' The file is actually located in C:\Users\janis\AppData\Roaming\elm\0.19.1\packages\NoRedInk\elm-json-decode-pipeline\1.0.0\elm.json See the 0.19.1 version part.

The weird thing is that it worked the first time I installed it (moments before I reinstalled it). Basically I installed the extension. It worked. Then noticed numbers next to elm files in file explorer and was wondering if that is extension feature or vscode feature (which I had just updated as well) as I couldn’t understand what they meant. Fastest way to check from where the features comes? Uninstall extension. Uninstalled it, numbers were gone. Ok, so that is extensions feature. Installed it back and it doesn’t work any more.

Then I found the ENOENT error and that I had two version folders inside AppData\Roaming\elm\packages\ - 0.19.0 and 0.19.1. Uninstalled both Elm versions. Deleted elm-spa-example project Deleted elm folder in AppData\Roaming Installed Elm 0.19.1 Cloned project again and built it, but the path is still as AppData\Roaming\elm\0.19.1\packages

Possible Solution

No solution, but seems that extensions is looking for packages in the wrong directory.

Yeah, I was just following the spa project instructions. Thanks for your help @Razzeee

Right, I always recommend to not use elm.js as windows finds this confusing https://github.com/evancz/guide.elm-lang.org/pull/244

Still, this is a new place to show this problem, as we just recently had to introduce that elm --version call
