MacOS下修改Python版本

安装

查看本机已安装的Python版本:where python3

~ where python3/usr/bin/python3/usr/local/bin/python3/Library/Frameworks/Python.framework/Versions/3.12/bin/python3

如果没有你想要的版本,去python官网下载安装包。

配置环境

防止踩坑:一般情况下大家的MacOS使用的是zsh ,所以不要去修改 base_profile
直接在~/.zshrc 配置文件添加如下内容:

1.编辑配置文件:vim ~/.zshrc

#python env confexport PYTHON_HOME=/Library/Frameworks/Python.framework/Versions/3.12export PATH=$PATH:$PYTHON_HOME/bin/python3# 别名,作用是你在命令行敲phthon即可,不用敲python3alias python=$PYTHON_HOME/bin/python3# pip别名alias pip=$PYTHON_HOME/bin/pip3

2.使配置生效 source ~/.zshrc

3.验证配置有效性

验证python 命令:python

~pythonPython 3.12.1 (v3.12.1:2305ca5144, Dec7 2023, 17:23:39) [Clang 13.0.0 (clang-1300.0.29.30)] on darwinType "help", "copyright", "credits" or "license" for more information.>>> print('hi, python!')hi, python!

再验证下 pip 命令:pip --version

pip --versionpip 23.2.1 from /Library/Frameworks/Python.framework/Versions/3.12/lib/python3.12/site-packages/pip (python 3.12)

That’s it!
