Can't import date-fns format

[GeorchW]

I think this is very similar to #9676, but I'm not 100% sure if it's the same (different error message, different versions etc) and I want to make a clean issue with a simple reproduction.

🐛 bug report

// test.js
import { format } from "date-fns";
format(new Date(), "dd.MM.yyyy");

Building this in watch mode with parcel test.js works, but running parcel build test.js will result in this error:

@parcel/core: node_modules/date-fns/index.js does not export 'format'

  test.js:1:10
  > 1 | import { format } from "date-fns";
  >   |          ^^^^^^
    2 | format(new Date(), "dd.MM.yyyy");

Adding --no-scope-hoist makes it work again, but that's quite a big thing.

🎛 Configuration (.babelrc, package.json, cli command)

Here's the package.json:

{
  "dependencies": {
    "date-fns": "^4.1.0",
    "parcel": "^2.13.3"
  },
  "type": "module"
}

🔦 Context

I've recently upgraded react-datepicker, which depends on date-fns. This issue is breaking the build for me, and I can't easily replace react-datepicker right now.

The --no-scope-hoist fix is not really an option I'd say. For now, I can hold back the upgrade, but if I don't find another solution, I might need to switch to another bundler -- at least for production.
