Environment

Operating System: Darwin
Node Version: v16.15.1
Nuxt Version: 3.0.0-rc.8
Package Manager: yarn@1.22.19
Builder: vite
User Config: -
Runtime Modules: -

Reproduction

https://stackblitz.com/edit/nuxt-starter-a2yhjt?file=app.vue

Describe the bug

Importing anything from the node_modules without explicit extension will return an error that module is not found. Here is the example of importing a function from lodash. However if I import it with the explicit extension like ‘lodash/cloneDeep.js’ everything works well.

Additional context

No response

I’m getting this with pinia on rc.8. In my server output when I yarn build, it ends up being import 'pinia/dist/pinia'; which fails to be able to load node_modules/pinia/dist/pina.mjs.

Cannot find module '/var/task/.output/server/node_modules/pinia/dist/pinia' imported from /var/task/.output/server/chunks/_..._.mjs

Adding pinia to transpile in the Nuxt configuration doesn’t seem to do anything. I’m guessing there’s something I can do with vite settings in the Nuxt configuration to get it to explicitly use .mjs, but I haven’t figured it out yet.
