# Install taxpasta on Apple Silicon

Issue: `biom-format` is not available as an `arm64` package

while running `mamba create -n taxpasta taxpasta=0.3`:

Encountered problems while solving:
  - nothing provides biom-format needed by taxpasta-0.3.0-pyhdfd78af_0

## Install Rosetta 2 if needed

If you haven't yet installed rosetta, you can install like so:

/usr/sbin/softwareupdate --install-rosetta

> you can add `--agree-to-license` to automatically agree to the license

## Create osx-64 taxpasta environment with conda/mamba
This creates a single environment using rosetta to run osx-64 packages. It stores those packages in a conda subdirectory called `osx-64`

CONDA_SUBDIR=osx-64 mamba create -n taxpasta python
mamba activate taxpasta
conda config --env --set subdir osx-64
python -c "import platform;print(platform.machine())" # should print: x86_64
mamba install taxpasta=0.3

You can alternatively see all settings for this environment using `conda info`

**The downside I can see for this method is that I don't (yet) know how to do this via an `environment.yml` file.**A

This might work, but I haven't actually tried it yet:

CONDA_SUBDIR=osx-64 mamba env create -f environment.yml 

# References

### per-environment setup
https://conda-forge.org/docs/user/tipsandtricks.html

Make sure that conda commands in this environment use intel packages.

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

To verify that the correct platform is being used, run the following commands after the environment has been activated:

python -c "import platform;print(platform.machine())"  # Should print "x86_64"
echo "CONDA_SUBDIR: $CONDA_SUBDIR"  # Should print "CONDA_SUBDIR: osx-64"
