moreati.uv.pip tries to use the Python module packaging. This doesn't exist by default, in a virtualenv created by uv.

Interested to hear what you think the solution is here. Maybe...

  1. Install packaging if it's not already in place.
  2. Adjust this repo to not require anything that packaging requires (maybe uv can provide 🙏🏻)
  3. Something else? 🤔

That's the goal, no plan or time scale yet. Best guess it may involve parsing the stdout of uv.

Add --dry-run to uv pip uninstall (#9557)
8d01f70 
## Summary

This proposes adding the command line option `uv pip uninstall --dry-run
...`, complementing the existing `uv pip install --dry-run ...` added
for #1244 in #1436.

This option does not exist in PyPA's `pip uninstall`, if adopted it
would be unique to `uv pip`. The code should be considered PoC, it is
baby's first Rust.

The initial motivation was while investigating
moreati/ansible-uv#2 - to allow Ansible module
`moreati.uv.pip` to work with`state: absent` in "check_mode" (Ansible's
equivalent of a dry run), without requiring `packaging` or `setuptools`.

## Test Plan

One new unit test has been added. I pedge to add more if the feature is
desired/accepted

Example usage

```console
➜  uv git:(pip-uninstall--dry-run) rm -rf .venv
➜  uv git:(pip-uninstall--dry-run) ./target/debug/uv venv                   
Using CPython 3.13.0
Creating virtual environment at: .venv
Activate with: source .venv/bin/activate
➜  uv git:(pip-uninstall--dry-run) ./target/debug/uv pip install httpx
