我在我的网站 example.com 上部署了 django-oscar 的示例应用程序沙箱。我想将其移至 example.com:8000 并在 example.com url 上运行另一个项目。我成功完成了第二部分,当你进入 example.com 时,你可以看到新的 django 项目启动并运行,但问题是,第一个 django 项目是 django-oscar 的沙箱,无法正常响应。

当您输入 example.com:8000 时,您会看到当前的调试日志:

现在我用谷歌搜索了这个错误,但没有得到任何有价值的结果。

另外,当我跑步时

sudo python manage.py migrate

发生以下情况,我也没有找到任何正确的解决方案来解决:

更新 1:我也为此使用 django 1.7.8。

更新 2:我将 Django 版本更改为 1.8.1,makemigrations 和 migrate 命令有效。然后我再次运行服务器,现在我的日志中出现了这个错误:(我还删除了 apache 设置,因为它们无关紧要!)

我终于可以解决我的问题了。问题是我使用 django 1.8 运行manage.py migrate并且该项目是在 django 1.7.1 下开发的,所以迁移破坏了。

所以我所做的是我再次安装了 django 1.8.1,运行manage.py migrate contenttypes 0001,然后卸载了 django 1.8.1,安装了 django 1.7.8 并运行manage.py runserver,一切恢复正常并且工作正常。

我遇到过同样的问题。就我而言,我使用 Django 1.10 创建本地数据库,但我需要使用旧的 Django 版本(1.7)进行一些测试,所以我删除了本地数据库并manage.py migrate使用 Django 1.7 运行,然后错误消失了。

或者,当项目使用 Django 1.10 运行时,可以保留数据库并在需要时将数据库移回项目,而不是删除本地数据库
