Pixi removing packages installed by `uv` not part of `pixi.toml`

[tadejsv]

I am installing a package from github (git+ssh://) using uv, as pixi does not support this yet. However, whenever I run any pixi command (even just pixi shell), this package gets uninstalled.

Is this really the desired behavior? Why not just issue a warning if non pixi-managed package is found? Or at least give an option to disable this behavior?

For now I am simply switching to installing with pip, which works, but is inferior to installing with uv

He @tadejsv, this is an good find.
This is most likely because we also use uv and "our" uv is getting the instruction to uninstall packages that are not needed anymore (based on requirements). As uv finds both pixi's and your uv packages it acts on them as equal.

@tdejager I know we're going to support all this behavior but would it be possible to make sure we only uninstall pixi installed packages? By making the INSTALLER uv-pixi or something like that.

I made a quick PR to uv here: astral-sh/uv#2561

I agree I think that would be the only option, it can potentially keep brealking for newer versions of pixi as long as people have not cleared their environments so we might need to add something to the release notes for that. Let’s hope uv accepts that PR soon :)

Uv has merged this so we should update and add the installer in the relevant places :)
