django - 无法修复 django.core.exceptions.AppRegistryNotReady：应用尚未加载

问题描述

我在 Docker 容器上运行以下代码行：

RUN python3 manage.py sitetree_resync_apps --settings=sites.production.settings

我收到以下错误：

Traceback (most recent call last):

我试图更新 Django 版本和其他几个库。错误会发生变化，但一旦最终修复，我总是会遇到上述错误！有人可以帮忙吗？

我在 manage.py 文件中找到了错误：

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "xxx.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

如果我注释掉 Dockerfile 中的违规行，则容器成功构建，但是当我尝试使用代码跳入它时：

 docker-compose up -d && docker-compose logs -f

我得到错误：


nettle_1  | Traceback (most recent call last):
nettle_1  |   File "manage.py", line 8, in <module>
nettle_1  |     from django.core.management import execute_from_command_line
nettle_1  | ImportError: No module named django.core.management
exited with code 1

我完全迷失在这里。

编辑你好梅尔文，这是我的 app.py

from mcvitty.site.signals import resource_event, notify_by_email
from django.apps import AppConfig

class InvoicingConfig(AppConfig):
    name = 'mcvitty.invoicing'
    verbose_name = "Invoices"

    def ready(self):
        resource_event.connect(notify_by_email, sender='invoicing.Invoice')

由于我缺乏使用 django 的经验，我仍然无法理解错误以及如何正确设置 app.py
