推荐使用brew安装

# brew search python3

==> Formulae
boost-python3                                                                            python@3.7                                                                               python@3.8 ✔

If you meant "python3" specifically:
It was migrated from caskroom/cask to homebrew/core.

然后执行安装

brew install python3
