Python版本为3.6.5, Django版本为2.1.7,,之前在本地迁移数据库的时候是很正常的,迁移到服务器上就报错,然后查看之后,发现本地数据库是5.7.22,服务端数据库版本为5.5.56,然后猜想为数据库版本问题,Django2.1生成的数据库语句和5.5版本的数据库不兼容.因此才会出现这样的错误.

之后查看了Django的发行信息

Djngo2.1只支持MySQL5.6(含)以上版本,所以确定就是MySQL版本问题.

并且,官方宣布,Django2.0是最后一个支持3.4版本的Python,还好我Python版本比较新一些.建议大家以后使用新版的时候,事先阅读一下新版本的新特性.嗯,就是这样
