Django / makemigrations ModuleNotFoundError: No module named 'idmp_core.apps.IdmpCoreConfigdjango';

Question

我正在学习 Django... 运行ning makemigrations 命令时出现一个我无法修复的错误。

我收到错误 ModuleNotFoundError: No module named 'idmp_core.apps.IdmpCoreConfigdjango'; 'idmp_core.apps' is not a package。令我困惑的是 django 单词附加在 idmp_core.apps.IdmpCoreConfig 字符串的末尾，它是

的一部分

INSTALLED_APPS = [
    'idmp_core.apps.IdmpCoreConfig'
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',

我的项目树结构如下：

D:.
|   manage.py
|   
+---idmp_core
|   |   admin.py
|   |   apps.py
|   |   models.py
|   |   tests.py
|   |   urls.py
|   |   views.py
|   |   __init__.py
|   |   
|   +---migrations
|   |       __init__.py
|           
+---idmp_v0
|   |   settings.py
|   |   urls.py
|   |   wsgi.py
|   |   __init__.py
|           
\---templates

我使用 python manage.py startapp idmp_core 创建了 idmp_core，一切顺利。

我修改了idmp_core目录的models.py。当我运行命令

python manage.py makemigrations idmp_core

我收到以下错误消息

(idmp) D:\Dropbox\mycode\idmp_v0>python manage.py makemigrations idmp_core

  File "<frozen importlib._bootstrap>", line 950, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'idmp_core.apps.IdmpCoreConfigdjango'; 'idmp_core.apps' is not a package

当我按照 Django 教程进行操作时，一切都很好。我做错了...但是我不明白在哪里...

你只是忘了在其中加一个逗号

给你

INSTALLED_APPS = [
    'idmp_core.apps.IdmpCoreConfig',
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

Django / makemigrations ModuleNotFoundError: No module named 'idmp_core.apps.IdmpCoreConfigdjango';
