# 查看所有 Python 安装路径
which python python3
# 检查 Python 版本
python --version
python3 --version
# 查看 Homebrew 安装的 Python
brew list | grep python

# 卸载 Python 3
brew uninstall [email protected] [email protected] [email protected] [email protected]
# 删除关联的链接
brew unlink [email protected]
# 清理残留文件
brew cleanup -s [email protected]
# 删除可能存在的配置文件
rm -rf /usr/local/bin/python3*
rm -rf /usr/local/bin/pip3*
rm -rf /usr/local/bin/pyenv*

# 删除主程序
sudo rm -rf /Library/Frameworks/Python.framework
# 删除应用
sudo rm -rf /Applications/Python\3.*
# 删除环境变量配置
nano ~/.bash_profile
nano ~/.zshrc
# 删除类似以下行：
# export PATH="/Library/Frameworks/Python.framework/Versions/3.11/bin:${PATH}"
# 删除残留文件
sudo rm -rf /usr/local/bin/python3
sudo rm -rf ~/Library/Python/3.*

# 查看已安装版本
pyenv versions
# 卸载特定版本
pyenv uninstall 3.11.4
# 完全移除 pyenv
rm -rf ~/.pyenv
# 清理 shell 配置文件
# 从 ~/.bash_profile, ~/.zshrc 等文件中删除 pyenv 相关行

# 官方卸载方法
conda install anaconda-clean
anaconda-clean --yes
rm -rf ~/anaconda3

# 检查默认 Python
which python
# 应指向 /usr/bin/python (系统自带)
which python3
# 应返回 "not found"
# 重建命令缓存
sudo /usr/libexec/path_helper

python -m venv myenv
source myenv/bin/activate

# 从 macOS 恢复分区获取
sudo cp /Volumes/macOS\ Base\ System/usr/bin/python2.7 /usr/bin/python
sudo ln -s /usr/bin/python /usr/bin/python2

# 检查 Python 命令
command -v python python3
# 检查残留文件
mdfind -name python | grep -v "/System/"
mdfind -name pip | grep -v "/System/"
# 检查环境变量
echo $PATH | tr ':' '\n' | grep python
