我正在尝试在我的本地机器上部署一个 Django 项目。据我所知，当我运行 migrate 命令时，my_app 表和 django 的表应该在我的本地数据库中可见。当我运行 makemigration app_name 命令时，我可以看到为我的表生成了正确的 SQL 查询。但是，当我运行 migrate 命令时，我得到了错误

表 'auth_user' 已存在

在我运行它之前，我的数据库是空的。我的迁移文件夹也只有init .py 文件。

以下是我得到的错误日志：

$ python manage.py migrate

The above exception was the direct cause of the following exception:

(env)

预期结果：我应该得到我的数据库中的所有表
实际结果：我得到 auth_user 表已经存在的错误。
