致电python manage.py migrate
时遇到此错误
第一次。我在窗户里。安装mysql,创建数据库,并放置数据库名称。
我使用的django version is 1.10.5
, python版本是python 3.7
,但系统中也有python 2.7
。
一些解决方案说Visual Studio开发人员工具可能会解决问题,我安装了Visual Stdio 2017开发人员工具,但问题仍然存在。

答案 0 :(得分:1)
我发现,必须安装特定版本的mysqlclient
才能解决这些错误。
我不得不卸载 python 3.7
(我发现可能存在一些问题)。
然后安装python 3.6.5.
然后安装mysqlclient 1.3.12
这两个没有冲突,并且项目运行顺利。
