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](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:

```bash
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

```
