I just downloaded version 9.24 of Modeller onto by macOS version 10.14.1
using Homebrew, but when I try to run the first few lines of the basic
tutorial, I get a lot of "command not found":

This is an alignment file. You're supposed to save this (using a text
editor) not "run" it at the terminal. I suggest you find and work
through a tutorial on using the terminal before you proceed.
Then when I try to do this (I am not sure what it is supposed to do, but
have been guaranteed that it works) I get:
Luos-Air:~ luoxiaoran$ cd /users/luoxiaoran/Documents/modAb101
This will change your current working directory.
Luos-Air:modAb101 luoxiaoran$ python3 modelAb101.py
Traceback (most recent call last):
File "modelAb101.py", line 2, in <module>
from modeller import *# Load standard Modeller classes
ModuleNotFoundError: No module named 'modeller'
Either something is broken in your Homebrew installation, or you have a
mismatch between the Homebrew Python and Apple's Python. Reading the
rest of your email though, it sounds like you may have seriously damaged
your operating system (you should not be deleting the Python framework).
You should probably reinstall the OS before you proceed.
