Feature request: --dry-run or something similiar for uv pip install

[notatallshaw]

I would like to test uv's ability to correctly resolve requirements, and in general it it sometimes useful to know how a package installer will install some requirements without actually installing them. An alternative to this would be uv pip download which is something I used to use a lot before --dry-run existed in Pip.

At the moment I am rebuilding my virtual environment each time. Maybe I am missing something and there is a supported workflow already?

Have you tried uv pip compile?

[charliermarsh]

It can also read from stdin, e.g. echo "black" | uv pip compile -.

Yes, this is sufficent for my purpose, thanks!
