应用如下命令装置：
brew install python@3.8装置好之后会有如下的输入：
Python has been installed as /opt/homebrew/opt/python@3.8/bin/python3Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to`python3`, `python3-config`, `pip3` etc., respectively, have been installed into /opt/homebrew/opt/python@3.8/libexec/binYou can install Python packages with /opt/homebrew/opt/python@3.8/bin/pip3 install <package>They will install into the site-package directory /opt/homebrew/lib/python3.8/site-packagesSee: https://docs.brew.sh/Homebrew-and-Pythonpython@3.8 is keg-only, which means it was not symlinked into /opt/homebrew,because this is an alternate version of another formula.If you need to have python@3.8 first in your PATH, run: echo 'export PATH="/opt/homebrew/opt/python@3.8/bin:$PATH"' >> ~/.zshrcFor compilers to find python@3.8 you may need to set: export LDFLAGS="-L/opt/homebrew/opt/python@3.8/lib"对于 LDFLAGS 请参考 ：https://www.cnblogs.com/taski...
