Django error 'ModuleNotFoundError: No module named 'ocore'

Question

Django 新手，刚刚开始按照教程构建新项目。

我创建了一个虚拟环境如下：

pip install virtualenv

virtualenv myproject_3_7_3

然后我激活虚拟环境并安装 Django，如下所示：

cd myproject_3_7_3

source bin/activate

pip install django

这会成功安装 Django 版本 3.2.10，然后我激活项目，添加一些文件夹结构并使用以下命令创建应用程序：

django-admin startproject myproject

cd myproject

mkdir apps

mkdir apps/core

python manage.py startapp core apps/core

然后我打开 VSCode，我可以在那里看到项目和所有默认 folders/files。

要启动应用程序我运行:

python manage.py startapp core apps/core

但我立即在终端中收到以下错误。

Traceback (most recent call last):
  File "/Users/myuser/myproject_3_7_3/lib/python3.7/site-packages/django/apps/config.py", line 244, in create
    app_module = import_module(app_name)

  File "<frozen importlib._bootstrap>", line 983, in _find_and_load
  File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'ocore'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "manage.py", line 22, in <module>
    main()
  File "manage.py", line 18, in main

    apps.populate(settings.INSTALLED_APPS)
  File "/Users/myuser/myproject_3_7_3/lib/python3.7/site-packages/django/apps/registry.py", line 91, in populate
    app_config = AppConfig.create(entry)
  File "/Users/myuser/myproject_3_7_3/lib/python3.7/site-packages/django/apps/config.py", line 250, in create
    app_config_class.__qualname__,
django.core.exceptions.ImproperlyConfigured: Cannot import 'ocore'. Check that 'apps.core.apps.OcoreConfig.name' is correct.

探索创建的apps.py显示如下内容：

from django.apps import AppConfig


class OcoreConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'ocore'

这与教程中给出的 apps.py 文件不同，所以我最初的想法是这可能是由于版本差异造成的，但是广泛搜索并没有得到关于 ocore 是什么或这个错误是什么意思。

有人能帮我解决这个问题吗？

拼写错误

我试图重现你的错误。

创建应用程序时，您错误地创建了名为“ocore”的应用程序。

但是在settings.py

INSTALLED_APPS = [
   ...
   apps.core, # This is what you added I presume
   apps.ocore, # this must be done
]

创建的应用程序名称应该与 django settings.py 中存在的 INSTALLED_APPS 数组中的名称相同。

还有一件事“startapp”只是为您创建具有所需文件和配置的目录结构。它不会运行你必须做的项目 python manage.py runserver
