FR: List and repair broken `uv tool` venvs (e.g. after a python upgrade). #8028

Open ilyagr opened 3 weeks ago

ilyagr commented 3 weeks ago

In the transcript below, I upgrade from Python 3.12.6 to 3.12.7 and all my uv tool install-ed tools break because the symlinks to python are broken. The problem is that uv can't handle these broken environments very well.

Currently, uv tool upgrade does not work as seen in the transcript. uv tool install works, but does not remember how the tool was installed originally, which is a problem if the tool needs a non-trivial command line to be installed correctly, e.g.:

# Commands like these are needed to work around `uv tool upgrade`
# not working.
uv tool install xonsh[full]
uv tool install marimo[sql] --with polars --with pandas  --with pyarrow \
                            --with matplotlib --with altair --with ruff
uv tool install --from \
   https://github.com/jjlee/git-meld-index/archive/release.zip git-meld-index

I would like either a uv tool repair command to repair such tools or for uv tool upgrade to be able to repair them. I'd also like uv tool list to work better for such tools.

Fortunately, the uv-receipt.toml file in the tool's venv already has all the needed info, so I'm guessing some feature like this was planned. (Let me know if there's already a way to do it that I missed!)

Related: https://github.com/astral-sh/uv/issues/1640, #7287. I feel like, even if those issues are solved, it'd still be nice if uv handled broken tool venvs better.

Yeah there's room for improvement here in general.

uv tool repair sounds kind of cool.
