elm-test doesn't work with Yarn 2

[Guara92]

Hi, I'm trying to migrate a project to yarn 2 (3.2.1) with PnP, but I have an issue when i try to run elm-test, everything works with yarn 1

node@project:/code$ yarn elm-test
/code/.yarn/unplugged/elm-npm-0.19.1-5-63dbdb9c23/node_modules/elm/bin/elm:1

`elm make` failed with exit code 1.

if I try to run it with npx, npx say that needs to install the package.

Update:
I tried with nodeLinker: node-modules and still doesn't work

Hi!

What happens if you run npx elm --help or yarn elm --help in the same directory?

elm-test just tries to execute elm and expects it to be in $PATH. npx and yarn add ./node_modules/.bin to $PATH, and people usually have elm in there so that’s how it works. But in your case, it looks like something expects node_modules/elm/bin/elm to be a Node.js script, while in reality it seems to be the Elm binary itself.

So from a quick look it doesn’t look like there’s a problem with elm-test – more of a problem of your installation of elm itself.

Thanks for your reply, I have the exact same result simply running elm.
I suspect more a yarn problem after your response, because if run the binary from its folder it works, i will try to open an issue on their side.

it's seems an old open issue on yarn side yarnpkg/berry#882 (comment)
