> conda update --all -c conda-forge Thank you @datpthus , I tried this but still got the same error

I did not find pyfes or fbriol in my anaconda navigator, is it the problem?

@datpthus Thank you! I think maybe pyfes does not support the MAC M1 chip. The file size of the anaconda installation package for the M1 was quite a bit smaller...
