Error installing on OS X Ventura 13

Issue

It seems like there is an error installing the matplotlib-base package on OS X Ventura 13 (possibly because the formatting of the version type of OS X has changed...?).

Here is the output of installing the crispresso2 package (in the bioconda channel, and I am a maintainer of the package).

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

Output in format: Requested package -> Available versions

Package python conflicts for:

  - feature:|@/osx-64::__osx==13.0=0
  - crispresso2 -> matplotlib-base -> __osx[version='>=10.11|>=10.12']

Your installed version is: 13.0

Note that this occurs on the M1 and M2 Apple Silicon chips, but is using the CONDA_SUBDIR=osx-64 environment variable to install the x86 versions of the packages. Also note that everything installs fine on M1 and M2 architecture with OS X Monterey 12.

Has anyone else run into this issue? Does it have something to do with the MACOSX_DEPLOYMENT_TARGET (found here in the recipe)?

I'm happy to submit a PR with a fix, but not sure where to start. If anyone has ideas on what to try, please let me know!

Installed packages

Issue occurs when installing package in new environment, so no packages are installed.

[dopplershift]

I'm installing fine locally on macOS 13.5. Can you try just installing matplotlib-base on your system? If that fails, does it work without bioconda?

[Colelyman]

Thanks @dopplershift! Interestingly enough installing just matplotlib-base (even with bioconda) works just fine. Do you know if there is an different check when matplotlib-base is installed individually or as a dependency?

[dopplershift]

Nope, the check is always the same. You might try doing the install of crispresso2 using mamba, which is conda-compatible but tends to give better diagnostics for conflicts. Also looking at the current output, you might want to poke around at the dependencies for bowtie2.
