I have been searching everywhere to try to find out about libpython3.x
I don't have libpython3.x on my machine and google searches made me more confused.

on my Machine I have
/Users/Jeff/.pyenv/versions/3.7.6/lib/python3.7/config-3.7m-darwin/libpython3.7m.a
/Users/Jeff/.pyenv/versions/3.7.6/lib/libpython3.7m.a

my $PATH is

/Users/Jeff/.rvm/gems/ruby-2.4.1/bin:/Users/Jeff/.rvm/gems/ruby-2.4.1@global/bin:/Users/Jeff/.rvm/rubies/ruby-2.4.1/bin:/Users/Jeff/.pyenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/Users/Jeff/.rvm/bin

so I have /Users/Jeff/.pyenv/shims in my path but neither of the above if these are the correct files

The only thing you have to do is: At least this solved the problem I had with the "libpython3.x library".
Good luck!

It might also be useful & effective to perform maintenance/upkeep with and That 'promotes' the whole OS-package to newest level.
