In case somebody else encounteres this, zarr can currently not be installed for Apple M1 machines and this gives a very weird error

conda create -n zarr-test zarr
Collecting package metadata (current_repodata.json): done

UnsatisfiableError:

when providing additionally python as a dependency I get

conda create -n zarr-test zarr python

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Output in format: Requested package -> Available versions

Package python conflicts for:
python
zarr -> python[version='>=3.5|>=3.6,<4']
zarr -> fasteners -> python[version='>=3.6|>=3.8,<3.9.0a0|>=3.9,<3.10.0a0']

Note, that the python dependency is solvable. In fact, pretty easily.

Digging a bit deeper revealed that numcodecs is not yet available on the platform but the messages above do not indicate this.

@conda-forge-admin, please update version

Currently we require numcodecs >=0.6.2. However in 2.4.0 this changes too numcodecs >=0.6.4.

@conda-forge-admin, please re-render.

@conda-forge-admin, please re-render.

Please re-render with conda-smithy version 1.3.2. This is needed to fix an issue where Travis CI bumped us from OS X version 10.9 to 10.11.

xref: conda-forge/conda-forge.github.io#249

@conda-forge-admin, please re-render.

Currently we require setuptools >18.0. However in 2.4.0 this changes too setuptools >=38.6.0.

In Zarr 2.4.0, we dropped Python 2 and associated backwards compatibility requirements. So we should make sure to drop those requirements from the recipe. This will also provide us an opportunity to make the recipe noarch: python. Though this will require we constrain python in host and run to be greater than or equal to 3.5 like so.

Solution to issue cannot be found in the documentation.

• I checked the documentation.

Issue

The minimum version specified to the conda-forge feedstock does not match the requirements of package, they need to be updated. Specifically the minimum required version of numcodec should be adjusted.
