django.db.utils.OperationalError: (2002, “Can‘t connect to local MySQL server through socket ‘/var/r

Django报错

问题：python3 manage.py makemigrations 时报错如下：

django.db.utils.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")

解决办法：

django 中settting.py中的DATABASE中的 HOST 修改为：

'HOST': '127.0.0.1',
 

原因：

If host is set to localhost, then a socket or pipe is used.
If host is set to 127.0.0.1, then the client is forced to use TCP/IP.
