I think pip install is standard procedure for python users. The reason I am building from source is because pip install failed.
Would you like to see the errors?
The problem you’re having is that you are missing some required build dependencies. These are found in the
build-system.requireskey of thepyproject.tomlfile.
Thank you.
Looking at that file reveals I am missing ‘cykhash’.
Never knew what that file was. That’s something new you taught me. Thanks. 
It’s installing now, after I installed ‘cykhash’.
PS
Would be nice if Python outputted an error message recommending checking that file for any missing dependencies.
