树莓派安装mysqlclient报错

pip install mysqlclient
错误信息

OSError: mysql_config not found
----------------------------------------ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

看网上的解答大部分是
sudo apt-get install libmysqlclient-dev，但是会报错

E: 软件包 libmysqlclient-dev 没有可安装候选

可以这样

sudo apt-get install python3-dev default-libmysqlclient-dev build-essential 

然后继续安装

 pip install mysqlclient

安装成功。
