@AriPerkkio can you help me with reproduction? (I remember you had one) I think this should also fix the version mismatch.

Using the reproduction setup from #3301 (comment).

With these changes I'm seeing the same error message as before:

And by removing these two commits in the reproduction setup (simple git reset HEAD~2 && git checkout .) I'm seeing the good old error message:

Error: Version mismatch: Vitest started as 0.31.4, but tests are collected with 0.40.0 version.

- If you are using global Vitest, make sure your package has the same version.
- If you have a monorepo setup, make sure your main package has the same version as your test packages.

With these changes I'm seeing the same error message as before:

Hm, workspace project root by default is still cwd 🤔

[sheremet-va]

Using the reproduction setup from #3301 (comment).

Works fine if I update vitest.workspace.js to the correct glob pattern: packages/*/{vite,vitest}.config.ts, so the idea is ok, but it doesn't work if users don't use workspaces :(

Another solution would be to always resolve Vitest to the root one ignoring package.json.

@AriPerkkio I found an elegant solution 🙈

@AriPerkkio I found an elegant solution 🙈

Turns out it doesn't work with workspaces 🙈
Because we have a different server, we cannot use resolve.dedupe there
