This has been the case for quite some time. Minimal repro here: https://github.com/GerkinDev/npm-completion-error

This makes npm very poorly usable in workspaces configuration in plumbing mode, at least for zsh. The issue can be somewhat mitigated in zsh by disabling plumbing mode & statically loading completion with something like:

source <(cd $HOME && npm completion)

Doing the above in the profile file effectively disable completion entirely in workspace packages, but at least, the error is gone.

Note: the cd ensure that you're not in a workspace package before running the command.

Unfortunately, with nvm, this becomes way less interesting.

Hope this gets fixed.

Was this fixed by this fix: ignore implicit workspaces for completion (#5932)?
