1. 第一步brew install mysql-connector-c

   brew install mysql-connector-c
   ==> Downloading https://mirrors.ustc.edu.cn/homebrew-bottles/bottles/mysql-client-8.0.21.catalina.bottle.tar.gz
   Already downloaded: /Users/caolipin/Library/Caches/Homebrew/downloads/3c778d3c5b4371d017c4453c26167d9d67555f58c62286d5fe2b4b8e2f338909--mysql-client-8.0.21.catalina.bottle.tar.gz
   ==> Pouring mysql-client-8.0.21.catalina.bottle.tar.gz
   ==> Caveats
   mysql-client is keg-only, which means it was not symlinked into /usr/local,
   because it conflicts with mysql (which contains client libraries).
   
   If you need to have mysql-client first in your PATH run:
     echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' >> ~/.zshrc
   
   For compilers to find mysql-client you may need to set:
     export LDFLAGS="-L/usr/local/opt/mysql-client/lib"
     export CPPFLAGS="-I/usr/local/opt/mysql-client/include"
   
   For pkg-config to find mysql-client you may need to set:
     export PKG_CONFIG_PATH="/usr/local/opt/mysql-client/lib/pkgconfig"
   
   ==> Summary
   🍺  /usr/local/Cellar/mysql-client/8.0.21: 135 files, 150.0MB
   

2. 下载后找到这个路径，/usr/local/Cellar/mysql-connector-c/6.1.11/bin这个路径，新版本找到这个路径是/usr/local/Cellar/mysql-client/8.0.19/bin，路径下有mysql_config这个文件，进入文件后发现第114行并不是网商其他教程那样的截图那样，是已经修改好的，应该是mysqlclient最新版本已经优化过了

3. 配置环境变量(上面安装日志告知了)

   export LDFLAGS="-L/usr/local/opt/openssl/lib"
   
   export CPPFLAGS="-I/usr/local/opt/openssl/include"
   
   export PATH="/usr/local/opt/mysql-client/bin:$PATH"
   

4. 重启终端

pip install mysqlclient
