Luos-Air:~ luoxiaoran$ which python3
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3
This is not Apple Python (/usr/bin/python3) or Homebrew Python
(/usr/local/bin/python3). Looks like you have a third version of Python
installed.
So I guess I am still not using Homebrew's Python -how do I switch to
using Homebrew's Python?
Run /usr/local/bin/python3 explicitly rather than just "python3". Or
edit your profile (maybe ~/.bashrc or ~/.zshrc) and remove
/Library/Frameworks/Python.framework/Versions/3.8/bin from your PATH.
Sorry, I just realized there are a few more things my friend
recommended I install, are these all okay to install?
