Problems installing with conda under MacOS 14.1 M1

I am trying to install bakta on my MacBook Pro 14" with an M1 processor. When I run

conda install -c conda-forge -c bioconda bakta

I get the error:

Found conflicts! Looking for incompatible packages.
This can take several minutes.  Press CTRL-C to abort.

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

Output in format: Requested package -> Available versionsThe following specifications were found to be incompatible with your system:

  - feature:/osx-arm64::__osx==14.1=0
  - feature:|@/osx-arm64::__osx==14.1=0

Your installed version is: 14.1

Can somebody help me understand what is going on? I think there is a problem with installing packages that bakta depends on.

Solution

Bioconda does not build for osx-arm64. Instead you must install from the osx-64, and macOS will run the software in emulation mode. That is, use:

## create a new environment
CONDA_SUBDIR=osx-64 conda create -n bakta_env -c conda-forge -c bioconda bakta

To safeguard against installing non-osx-64 software in this environment, I recommend subsequently setting the subdir for the environment's configuration:

conda activate bakta_env
conda config --env --set subdir osx-64
