我对django很陌生。我用pythonv3.6和django v2.1创建了一个示例项目。最初,我使用的是默认的sqlite3数据库,但现在我们计划将其改为mysql。为此,我安装了所有必要的插件。另一方面,除了admin之外,我没有用sqlite3创建任何表。
如果它是在默认数据库中,当我将其更改为mysql时,它可以正常工作。我得到了一个星期内无法解决的错误:-(

我也遇到了同样的问题,继续这样做:
安装更新版本的sqlite3,即3.2.0
删除db.sqlite3(之后我没有创建新的)
run command : python manage.py migrate
python manage.py runserverpython manage.py createsuperuser
登录,然后添加新用户或在模型表中添加一些内容。祝你好运
