Installation failure - Mac

[Lseg]

Hi,

I am trying to install QIIME on a Mac (Ventura).
After having installed miniconda3, I updated it
conda update conda

but then when I type
conda env create -n qiime2-amplicon-2024.10 --file https://data.qiime2.org/distro/amplicon/qiime2-amplicon-2024.10-py310-osx-conda.yml

I get an error that I don't know how to solve. I am only showing the beginning:
"LibMambaUnsatisfiableError: Encountered problems while solving:

• nothing provides requested vsearch 2.22.1**
• nothing provides requested unifrac-binaries 1.4**
• nothing provides requested unifrac 1.3**
  ...
  ...
  Could not solve for environment specs
  The following packages are incompatible
  ├─ bioconductor-ancombc 2.4.0** is not installable because it requires
  │ └─ r-energy, which does not exist (perhaps a missing channel);
  ├─ bioconductor-beachmat 2.18.0** does not exist (perhaps a typo or a missing channel);"

My conda version is conda 24.9.2.

Thank you in advance,
Laure

Helle @Lseg,

Welcome to the forums! :qiime2:

Can you run conda info and post the result?

When I saw this

@Lseg

r-energy, which does not exist (perhaps a missing channel);

it made me think that a channel was missing, and conda info will tell us what channels you have configured on your Mac.

Hey @Lseg,

I suspect you are on apple silicon, as the missing package list looks just about like the ones that don't have ARM builds yet.

Try these instructions instead:

CONDA_SUBDIR=osx-64 conda env create -n qiime2-amplicon-2024.10 --file https://data.qiime2.org/distro/amplicon/qiime2-amplicon-2024.10-py310-osx-conda.yml
conda activate qiime2-amplicon-2024.10
conda config --env --set subdir osx-64

Yes, that works ! Thanks so much,
Laure
