Python Django Sqlite3编程错误

我对Django很陌生。我已经用PythonV3.6和DjangoV2.1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，我没有使用sqlite3创建任何表

当我将其更改为MySQL时，如果它位于默认数据库中，则工作正常。我遇到了一个一周内无法解决的错误：-(

请让我知道我的

出了什么问题，我也遇到了同样的问题，请按以下方式继续：

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命令：python manage.py migrate

python manage.py runserver

python manage.py createsuperuser

登录，然后添加新用户或在模型表中添加内容

祝你好运

你想从哪里运行Django服务器？IPython是如何参与的？@Cyrlop我正在Windows 7中运行我的Django你的MYSQL中有名为

shield\u dev

的数据库吗？@jerinterGeorge没有，我没有。我有Ruby on Rails的经验，所以在这个框架中，它会自动为我们创建数据库。这就是我为什么没有这样做的原因'不要手动创建数据库。请检查您的mysql数据库
