@babel/preset-env/lib/utils has been removed

[markhoney]

Bug Report

• I would like to work on a fix!

Current behavior

Nuxt JS relies on @babel/preset-env/lib/utils, which appears to have been removed in version 7.13

Input Code

Expected behavior

Babel Configuration (babel.config.js, .babelrc, package.json#babel, cli command, .eslintrc)

• Filename: babel.config.js

Environment

• Babel version(s): v7.13.0
• Node/npm version: Node 14
• OS: macOS 11.2.1
• Monorepo: Lerna
• How you are using Babel: webpack

Possible Solution

Re-add the file utils.js to @babel/preset-env

Hey @markhoney! We really appreciate you taking the time to report an issue. The collaborators on this project attempt to help as many people as possible, but we're a limited number of volunteers, so it's possible this won't be addressed swiftly.

We can check if we can add a stub back to restore the original functionality, but that file has never been part of the public API.

Adding it back in, for now, would be great, as I'm sure there will be a few Nuxt users who are going to have issues with this. In the long term, hopefully Nuxt will work around this.

Ok it looks like it's easier to make a PR to remove that usage in Nuxt.js, I think I'll do that instead.

Closing this issue as nuxt/nuxt#8883 is merged. Importing internal Babel files will throw on Babel 8, as we mentioned in Babel 8 release plan

If anyone else is relying on internal Babel files, please let us know!
