Can confirm, the same issue for us.

ERROR in ./.nuxt/client.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):

@bkuri Would you try recreating your lock file to see if the error persists? If so, would you provide a reproduction? 🙏

Note: Related to #9631.

I encountered the same problem and managed to solve it by recreating yarn.lock. Thanks!

node version: v12.16.3

Part of my package.json:

{
  "dependencies": {
    "@babel/core": "^7.15.0",
    "@babel/preset-env": "^7.15.0",
    "@nuxt/types": "^2.15.8",
    "babel-core": "^7.0.0-bridge.0",
    "babel-jest": "^27.0.6",
    "nuxt": "^2.15.8",
    // ......
  },
  // ......
}

@danielroe looks like that fixed it. Thanks!

If you don't want to nuke your whole yarn.lock, you can delete just the @babel/... portions of it and then run yarn install again. It will recreate just the Babel parts. This resolved the issue for me.
