Fail to resolve a package

[noamgot]

[Orignally asked on discord]

I need to install a package called "alpha-shape". It's an internal package within my organization. I don't think the problem I describe here is a channel issue, as I managed to install many other internal packages from the channel where this package is stored.

I tried installing it with version>=1 in a clean pixi project and got an error:

Without the version constraint, I managed to install it with version 0.0.10 (I must use version >=1 though).

I ran pixi add with -vvv , here are the relevant logs:

Installing this package with a regular mamba create command works properly:

mamba create -n dummy "alpha-shape>=1" --dry-run

If that helps, here are the results of pixi info alpha-shape:

What could be the issue here? I don't even know where to start... thanks

Could you check the conda-meta/alpha-shape-....json file in the folder of the mamba environment?

It feels like this should contain a constraints list. Which would explain the pixi result. e.g. something like this:

{
...
  "constrains": [
    "alpha-shape 1010.6.*",
  ],

Could you share this file?

indeed, there's a constraints section with alpha-shape itself. I don't understand how it works with mamba but not with pixi...
