mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')

everytime I call the phylophlan command (even phylophlan --v) I get this error.

Traceback (most recent call last):

I have a M1 macbook pro.
Metaphlan works ok

Hi, reading through the error you reported it feels to me that there is a problem with the Biopython library. Please, check if there exists a Biopython version compatible with your architecture, otherwise, you should consider using a different machine with a compatible architecture.

Many thanks,
