我想开始学习Django框架,但我已经遇到了问题。我已经设置了Django和一切,但是当我到达运行服务器时,我的问题已经开始了。在我编写python manage.py runserver
之后:
C:\Users\Programiranje\Desktop\Django\mysite> python manage.py runserver
它会抛出这样的异常:
Performing system checks...

我有一个类似但却没那么有帮助的错误信息:
System check identified no issues (0 silenced).
Unhandled exception in thread started by <function wrapper at 0x00000000051F2518>

这是由于我的某个应用迁移文件夹中存在合并迁移引起的,这些迁移文件夹引用了不存在的迁移。迁移引用了来自另一个VCS分支的其他迁移,并且是由同事意外提交的,我已将其合并到我的分支中。
在此发布答案,因为这是有关此主题的最明显的问题。

我遇到了类似的问题,这是因为我使用的是django的旧版本。 如果您使用的是Mac,请运行以下命令:
1。删除当前的django版本并安装最新的稳定版本。
pip3 install -U django
2。应用迁移(如果有)。确保在您的项目目录中运行此命令。
python3 manage.py migrate
3。在本地端口8000上启动服务器。
python3 manage.py runserver
干杯!
答案 3 :(得分:-2)
如错误所示,您尚未应用迁移。
只需运行python manage.py migrate
即可。这就足够了。
