Cannot uninstall any package: `Pipx Internal Error: cannot find package {root_req.name!r} metadata.`

Describe the bug I cannot use my packages after some upgrade:

$ pre-commit run --all
Traceback (most recent call last):
  File "/home/juanlu/.local/bin/pre-commit", line 5, in <module>
    from pre_commit.main import main
ModuleNotFoundError: No module named 'pre_commit'

so I went to see what was going on:

$ pipx list
venvs are in /home/juanlu/.local/pipx/venvs
apps are exposed on your $PATH at /home/juanlu/.local/bin
⚠️  package black[jupyter] has missing internal pipx metadata.
⚠️  package docker-compose has missing internal pipx metadata.
⚠️  package isort has missing internal pipx metadata.
⚠️  package nox has missing internal pipx metadata.
⚠️  package orchest-cli has missing internal pipx metadata.
⚠️  package pdm has missing internal pipx metadata.
⚠️  package pre-commit has missing internal pipx metadata.
⚠️  package rst-to-myst[sphinx] has missing internal pipx metadata.
⚠️  package tox==4.0.0b2 has missing internal pipx metadata.

One or more packages have a missing internal pipx metadata.
   They were likely installed using a pipx version before 0.15.0.0.
   Please uninstall and install these package(s) to fix.

But nothing worked:

Expected behavior Uninstall works.

Actually reinstall-all won’t work in your case. This issue is a duplicate of #278.

Well, my expectation is that a full reinstall will work 🙃 I was holding that off in case I could help uncover some underlying bug by digging a bit more. I’ll proceed with that solution.
