Installing into miniconda with conda-forge

I'm trying to install SPAM via installing into miniconda with conda-forge section. When I run "mamba install spam", Errors ( "Pinned packages:

python 3.9.* Could not solve for environment specs Encountered problems while solving:
nothing provides requested spam The environment can't be solved, aborting the operation__ ") appears after "conda-forge/noarch". By the way, I don't know whether this issue is related to python version (3.9) or macbookpro edition (M1 pro). Look forward to your reply.
