我正在学习 Django... 运行 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”不是包。令我困惑的是 django 词附加在 idmp_core.apps.IdmpCoreConfig 字符串的末尾，它是
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目录下的models.py。当我运行命令时
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

ModuleNotFoundError: No module named 'idmp_core.apps.IdmpCoreConfigdjango'; 'idmp_core.apps' is not a package
当我学习 Django 教程时，一切都很好。我做错了......但我不明白在哪里......
请您参考如下方法:
你只是忘了在里面放一个逗号
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',
]
