Conda missing package for Mac M3

[luigallucci]

Hi,

I'm facing issues in installing chopper through conda...using bioconda channels give a missing package result.

Actually, I got the main problem is the distribution...as mac from M processor series are arm processor, the package is actually available for osx-64 platform. Even setting bioconda correctly, the only way to install it is to have an environment set to osx-64 instead of osx-arm64:

mamba create -n chopper --platform osx-64 -c bioconda chopper

This actually solved problem of installation, hope can be helpful for others...sorry for the "not useful" issue.

Ah, thanks for letting me know, and sharing the solution. I will see if this is something I can fix...

this should be fixable by changing the recipe in the bioconda-recipes. I believe something like this would work

`{% set version = "0.9.0" %}

package:
name: chopper
version: {{ version }}

build:
number: 0
run_exports:
- {{ pin_subpackage('chopper', max_pin="x.x") }}
skip: false # [not (linux-64 or osx)]
platforms:
- linux-64
- osx-64
- osx-arm64
