Describe the bug

If I run nuxi upgrade, the following happens:

~/Entwicklung/Nuxt/example-frontend git:[next_gen]
nuxi upgrade

have the most up-to-date dependencies?
Yes

After that, the lock file is empty, too.

It does not happen, if I use --no-force

Would you be able to provide a reproduction? 🙏

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritize it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

We have a couple of templates for starting with a minimal reproduction:

👉 https://stackblitz.com/github/nuxt/starter/tree/v3-stackblitz
👉 https://codesandbox.io/s/github/nuxt/starter/v3-codesandbox

A public GitHub repository is also perfect. 👌

Please ensure that the reproduction is as minimal as possible. See more details in our guide.

I am not sure how to provide a reproduction on something that fails after console action.

[ahoiroman]

At least I added all dependencies similar to my project: https://stackblitz.com/edit/github-k9m8kagr?file=package.json

Additional information: This does only happen un nuxt > 3.14.0

The upgrade command removes the node_modules directory halfway through its execution (when accepting the force prompt or passing --force), which I think is what causes the Cannot find module error.

I'm guessing that this was not an issue before #618, which changes the dependency installation to use nypm, which uses a dynamic import which resolves to undefined since the node_modules directory was removed (https://github.com/unjs/nypm/blob/main/src/_utils.ts#L40).

Using pnpx nuxi upgrade should work as expected as a temporary workaround until this issue is resolved.

[BobbieGoede]

The underlying issue has been resolved from within nypm (unjs/nypm#182) which will be included in the next release, so I'm closing this!
