解决方案

1. 在Mac 使用brew安装 mysql-connector-c

brew install mysql-connector-c

2. 查找mysql_config的位置

(venv1) ➜  bin find / -name mysql_config
find: /usr/sbin/authserver: Permission denied
/usr/local/mysql-8.0.27-macos11-arm64/bin/mysql_config

3. 打开.bash_profile配置文件

vi ~/.bash_profile

4. 将/usr/local/mysql-8.0.27-macos11-arm64/bin/mysql_config配置到环境变量中

 1 PATH=/bin:/usr/bin:/usr/local/bin/:/usr/local/mysql-8.0.27-macos11-arm64/bin/:${PATH}
 2 export PATH

5. 使新配置的~/.bash_profile生效

(venv1) ➜  bin source ~/.bash_profile

7. 测试是否成功

(venv1) ➜  bin pip install mysqlclient
