Django执行数据库迁移报错

执行python manage.py makemigrations blog报错

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.Did you install mysqlclient?

解决：在项目目录init.py文件中添加

import pymysql
pymysql.install_as_MySQLdb()

再次执行python manage.py makemigrations blog报错

django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.2.

解决：将init.py文件中添加pymysql.version_info=(1,3,13,"final",0)

import pymysql
pymysql.version_info=(1,3,13,"final",0)
pymysql.install_as_MySQLdb()

再次执行python manage.py makemigrations blog

    blog/migrations/0001_initial.py;
