django2.2 对接pymysql

借鉴 https://blog.youkuaiyun.com/lpw_cn/article/details/103978909

迁移发现仍报错

File "C:\ProgramData\Anaconda3\envs\django2.2py3.6\lib\site-packages\django\db\backends\mysql\operations.py", line 146, in last_executed_query
    query = query.decode(errors='replace')
AttributeError: 'str' object has no attribute 'decode'

网上很多答案都是修改源码然而并不用的，只需要安装mysqlclient即可。

步骤

1.pip uninstall pymysql将对接的pymysql卸载，并删除对接msyql的代码

# import pymysql
# pymysql.install_as_MySQLdb()

2.pip install mysqlclient
cenos安装 可能需要 先装环境

sudo yum install python3-devel mysql-devel
