bug(upgrade): fails for platform-specific targets #4297
Description
Checks
-
I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pixi, using
pixi --version.
Reproducible example
$ pixi init example && cd example
$ pixi add --platform linux-64 'python 3.12'
$ pixi upgrade[workspace]
channels = ["conda-forge"]
name = "example"
platforms = ["linux-64"]
version = "0.1.0"
[tasks]
[dependencies]
[target.linux-64.dependencies]
python = "==3.12"Issue description
Description
It seems that (for Pixi v0.50.2) if a Pixi manifest is created that has a platform specific target then pixi upgrade fails for the manifest, though pixi update works.
Example
If I start by creating the following Pixi manifest
$ pixi init example && cd example
$ pixi add 'python 3.12'[workspace]
channels = ["conda-forge"]
name = "example"
platforms = ["linux-64"]
version = "0.1.0"
[tasks]
[dependencies]
python = "==3.12"then I can upgrade it with pixi upgrade
$ pixi upgrade

channels = ["conda-forge"]
name = "example"
platforms = ["linux-64"]
version = "0.1.0"
[tasks]
[dependencies]
python = ">=3.13.5,<3.14"However, if I now create this same manifest but create a platform specific target
$ pixi init example && cd example
$ pixi add --platform linux-64 'python 3.12'[workspace]
channels = ["conda-forge"]
name = "example"
platforms = ["linux-64"]
version = "0.1.0"

[target.linux-64.dependencies]
python = "==3.12"then pixi upgrade fails to upgrade.
