picrust2 installation error on mac m2

Looking for: [‘picrust2=2.5.2’]

Could not solve for environment specs

The following package could not be installed

└─ picrust2 2.5.2**  is uninstallable because it requires

   └─ biom-format >=2.1.10 , which does not exist (perhaps a missing channel).

And when I try to install from source, I get this error:

Looking for: [“biom-format[version=’>=2.1.10′]”, ‘cython’, ‘epa-ng=0.3.8’, ‘gappa=0.8.0′, “glpk[version=’>=4.65′]”, “h5py[version=’>=2.10.0′]”, “hmmer[version=’>=3.1b2,<=3.2.1′]”, “jinja2[version=’>=2.11.3′]”, “joblib[version=’>=1.0.1′]”, “numpy[version=’>=1.19.5′]”, “pandas[version=’>=1.1.5′]”, “pytest[version=’>=4.4.1′]”, “pytest-cov[version=’>=2.6.1′]”, “python[version=’>=3.5,<3.9′]”, “r-base[version=’>=3.5.1′]”, “r-castor[version=’>=1.7.2′]”, “scipy[version=’>=1.2.1′]”, ‘sepp=4.3.10’]

Could not solve for environment specs

The following packages are incompatible

├─ biom-format >=2.1.10  does not exist (perhaps a typo or a missing channel);

├─ epa-ng 0.3.8**  does not exist (perhaps a typo or a missing channel);

├─ gappa 0.8.0**  does not exist (perhaps a typo or a missing channel);

├─ hmmer >=3.1b2,<=3.2.1  does not exist (perhaps a typo or a missing channel);

├─ r-castor >=1.7.2  does not exist (perhaps a typo or a missing channel);

└─ sepp 4.3.10**  does not exist (perhaps a typo or a missing channel).

Any seasoned advice for a newbie would be greatly appreciated!

best,
