element-plus: [Bug Report] [All] Uncaught SyntaxError: The requested module '/_nuxt/node_modules/dayjs/dayjs.min.js?v=391d0c11' does not provide an export named 'default' (at picker2.mjs?v=391d0c11:2:8)

dayjs

If you encounter this issues, you can try adding dayjs to the nuxt.config

export default defineNuxtConfig({
vite: {
    optimizeDeps: {
      include: ['dayjs', 'dayjs/plugin/*']
    }
  }
})

It’s still keep the same issue.

  }
})

I’ve reproduced it here: https://stackblitz.com/edit/github-spueta?file=app.vue Please note that the code about time picker is in app.vue:

<ElDatePicker />

Also, there are two package-lock.json file, one is named as package-lock-backup.json. This issue will be reproduced with package-lock.json and not with package-lock-backup.json

Commands:

rm -r node_modules .nuxt
npm i
npx nuxt prepare

Please note that this may not be produced on Windows

Please reproduce it in stackblitz, I also cannot reproduce it on local machine.

Yes I agree that may related to dependencies, and the elemen-plus version remains the same, but it’s hard to locate the issue.

At present, the dayjs is based on CommonJS Modules. It seems that there is a conflict when you use unplugin-vue-components like this. Maybe you need to manually introduce required components like template. Wait for the dayjs dependency upgrade to 2.0.
