Hmm 🤔
This is strange... rollup v4.18 could not import resources in relative paths...

I've added console.log on unplugin-vue-i18n.
I've faced the below log:

resolveId ../../../layers/layer-server/app/locales/en.json5 /path/to/Projects/oss/nuxt/i18n/specs/fixtures/basic_usage/.nuxt/___basic_usage_spec_ts/i18n.options.mjs
resolveId ../../../layers/layer-server/app/locales/en.json5 /path/to/Projects/oss/nuxt/i18n/node_modules/.pnpm/[email protected]_@[email protected]_@[email protected]_@types+no_3dkmkqqbk22rzp2kskenwj4dky/node_modules/nuxt-nightly

I can't understand why en.json5 is importing from nuxt-nightly. 😅

This is due to the folder structure changes in Nuxt 4, I have changed the fixture configurations to use the same structure as Nuxt 3 did using the example shown here.

The tests will still fail due to other factors, which should be resolved with #3015. I made a branch that's rebased on that PR (and main) to demonstrate here: BobbieGoede#46.

@kazupon
I have updated/rebased this branch, it looks like it's mostly working except for the nested fixtures.. All fixtures inside specs/fixtures/issues fail with Error: Cannot find module '@nuxtjs/i18n' 🤔

Fixing this required adding the following to pnpm-workspace.yaml:

- 'specs/fixtures/issues/*'

Not sure why or how it previously worked without issue 🤔 but it looks like all tests succeed now 💪

@BobbieGoede
Thanks!
Oh, I missed the srcDir change ... 🤦‍♂️

The build of the nuxt docs is failing. It seems that nuxt modules that depend on them have not yet been released in a version compatible with nuxt 4.
