brew install mysql-connector-c
xcode-select --install
brew install openssl
安装后终端会显示配置环境变量方法
If you need to have openssl@3 first in your PATH, run:
echo 'export PATH="/opt/homebrew/opt/openssl@3/bin:$PATH"' >> ~/.zshrc
For compilers to find openssl@3 you may need to set:
export LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include"
brew unlink mysql
brew link --overwrite mysql-connector-c
如图连接mysql-connector-c有警告
Warning: mysql-client is keg-only and must be linked with --force.
执行
brew link --overwrite mysql-connector-c --force
使用pip install mysqlclient不会出现任何错误
做取消链接MySQL和链接的MySQL连接器mysql-connector-c相反的操作：
brew unlink mysql-connector-c
brew link --overwrite mysql --force
