操作

sudo install_name_tool -change  libmysqlclient.21.dylib /usr/local/mysql/lib/libmysqlclient.21.dylib /Library/Python/2.7/site-packages/_mysql.so

然后报错

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/w6/l9krf1yd1bb_0t3m5bhw_w500000gn/T/pip-build-5ytzox4k/mysqlclient/

解决办法：

先brew安装mysql-connector

brew install mysql-connector-c

# 修改前先备份

cp  mysql_config mysql_config_backup
# 修改编辑权限
chmod 777 mysql_config
vi mysql_config
# 修改114行
> # Create options 
> libs="-L$pkglibdir"
> libs="$libs -l "
# 修改为
> # Create options 
> libs="-L$pkglibdir"
> libs="$libs -lmysqlclient -lssl -lcrypto"

然后pip3 install mysqlclient

mysqlclient连接数据库时报错：

django.db.utils.OperationalError: (2059, "Authentication plugin 'caching_sha2_password' cannot be loaded: dlopen(/usr/local/Cellar/mysql-connector-c/6.1.11/lib/plugin/caching_sha2_password.so, 2): image not found")

解决：

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'mima'
