python - Heroku 中的 Django 部署 : Fails in createsuperuser : django. db.utils.OperationalError:没有这样的表:auth_user

Question

有很多关于这个特定错误的 stackoverflow 问题，但我认为没有人遇到与我类似的情况。我一直在关注 djangogirls heroku 部署教程，从 settings.py 中的数据库设置确保我已经正确完成了它。

我在主机中启动并运行了应用程序。现在尝试访问 admin，仍然出现 auth_user 的操作错误。因此我认为我的迁移可能出了问题。因此，按照以下步骤我这样做了:

1.) python manage.py makemigrations

2.) python manage.py 迁移

3.) git add . , git commit -m "-", git Push heroku master

4.) heroku run python manage.py makemigrations

5.)heroku run python manage.py migrate

现在到了最后一步，这里一切都失败了，说还有东西要迁移。

6.)heroku run python manage.py createsuperuser

我所做的步骤是他们提出并被接受的建议，但它似乎不适用于我的情况。有什么想法吗？

heroku run python manage.py showmigrations

此时似乎已经错了。Migrations 表示已应用，但 showmigrations 表示不然

You have 16 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, blog, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

最后，我重新进行了整个设置，一切顺利，没有任何问题。无论如何，将问题保留在这里，以防万一有人遇到同样的问题，并且最终会得到更好的答案。
