Complete output from command python setup.py egg_info:
    /bin/sh: 1: mysql_config: not found
    Traceback (most recent call last):

        metadata, options = get_config()

        libs = mysql_config("libs_r")
      File "/tmp/pip-install-7qo1k7as/mysqlclient/setup_posix.py", line 28, in mysql_config

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-7qo1k7as/mysqlclient/

sudo apt-get install mysql-server mysql-client
然后mysql -V查看mysql是否安装成功
sudo  apt-get install libmysqlclient-dev python3-dev
然后
pip install mysqlclient就不会报错找不到‘mysql_config‘了

 mysql> CREATE DATABASE office DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
 
 mysql> grant all privileges on office.* to office@‘%‘ identified by ‘office‘;

 mysql> flush privileges;

set password for root@‘localhost‘=password(‘xxxx‘);
