uv pip install --verbose not displaying native extension build logs

[abetlen]

Hi there!

First off fantastic project, I'm currently in the process of moving over most of my ci to uv but I just ran into a little issue regarding logging build information for native extensions.

Issue

When building and installing native extensions it's commonly useful to print verbose logs from the build steps (usually cmake logs). With pip adding --verbose seems to be sufficient to get these logs printed however with uv pip I haven't been able to get them to print no matter what options I set (maybe I'm doing something wrong).

Minimal Example

python3 -m pip install uv
git clone https://github.com/scikit-build/scikit-build-core.git
cd scikit-build-core/docs/examples/getting_started/c
# Installing using pip --verbose prints cmake logs
pip install --verbose --editable .
# However with uv pip it does not
uv pip install --verbose --editable .

Expected Output

  *** scikit-build-core 0.8.2 using CMake 3.28.3 (editable)

Thanks for the well written issue :)

Is this a duplicate of either

• Verbosity level to see output from build backend #2146
• A way to get sub-command output when running uv pip install #1567

or is it different somehow?

@zanieb woops, yes sorry it is a duplicate. I did search first but I guess I missed those somehow. I'll close this issue!
