I downloaded a yml file and converted it to the pixi format:
wget https://raw.githubusercontent.com/qiime2/distributions/refs/heads/dev/2025.7/amplicon/released/qiime2-amplicon-macos-latest-conda.yml
pixi init --import qiime2-amplicon-macos-latest-conda.yml
I edited this part:
platforms = ["osx-64"]
Then pixi install
Miraculously, it made it through the install but missed some R software, including the historic problem bioconductor-genomeinfodb
So close!
Interesting, do they not run post-link hooks? That's where our nemesis lives.
EDIT: check out this:
That might solve it.
I tried again, and this time it works!
wget https://raw.githubusercontent.com/qiime2/distributions/refs/heads/dev/2026.4/amplicon/passed/qiime2-amplicon-osx-64-conda.yml
pixi init --platform osx-64 --import qiime2-amplicon-osx-64-conda.yml
✔ Created /Users/colin/bin/github/pixi_demo/pixi.toml
pixi run qiime info

I'll test it out more and see if it can replace conda
