Django项目与mysql交互进行数据迁移时报错：AttributeError: 'str' object has no attribute 'decode'

问题描述

Django项目启动，当我们执行命令 python manage.py makemigrations 出现如下错误：

  File "/usr/local/lib/python3.6/dist-packages/django/db/backends/mysql/operations.py", line 147, in last_executed_query
    query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

 解决办法

顺着报错信息，找到报错的位置，把

query = query.decode(errors='replace') 修改成 query = query.encode(errors='replace')
