Weird error in synced environment

[simonh1000]

I use a sync program to keep my to dev computers in sync. It works in general, but I experience issues with elm-test, as when I switch from one computer to another, elm-test fails until I delete the elm-package directories (seemingly in both the root and tests directories). What I see is

Unhandled exception while running the tests: { Error: EEXIST: file already exists, symlink '/Users/.../tests/elm-stuff' -> '/Users/.../elm-stuff/generated-code/elm-community/elm-test/elm-stuff'

I'm 99% sure this is not an issue with elm-test. We're not touching the elm-stuff directory ourselves. Is it possible for you to exclude elm-stuff from synchronizing? It's very likely to contain per-computer data, so it should be generated locally on each device.

[simonh1000]

yes I do. I have changed the setting to avoid that and will report back when I have more data

I'm not using any kind of synced environment; just using NPM and having the same problem.

[simonh1000]

all I can add is that the frequency does seem to have gone down significantly, but I did still get the error again recently while using my other device. Had to delete all elm-stuff directories

[drathier]

Correction: the node test runner does modify elm-stuff, to add some generated elm files.

We are also experiencing this issue, though we are using Docker which might result in a similar situation as syncing multiple computers. Removing /project_root/elm-stuff and /project_root/tests/elm-stuff did help.

I'm in the same boat, running [email protected]. I have no sync running but my path setup is atypical (because of Webpacker) but I have some private packages installed using elm-install. Not sure if it's related, I suspect the unusual path setup because before migrating to Webpacker, with normal setup (src/ and tests/ side by side) it worked.
