conda install unsuccessful

[ethering]

Hi,
Should pirs still be available through conda? I'm having problems trying to install it on Mac OS (v13.5):

conda create --name parsley python=3.8
conda activate parsely
conda install -c bioconda pirs
Collecting package metadata (current_repodata.json): done
Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve.

Trying with pip is also turning out to be a bit of a nightmare too (sklearn deprecation issues), but I'd prefer to stick to conda anyway.
Any help would be gratefully appreciated.
