Django/makemigrations ModuleNotFoundError:没有名为“idmp”的模块_core.apps.IdmpCoreConfigDjango';

Question

我在学Django。。。在运行makemigrations命令时，有一个错误我无法修复。在

我得到错误ModuleNotFoundError: No module named 'idmp_core.apps.IdmpCoreConfigdjango'; 'idmp_core.apps' is not a package。让我困惑的是django单词出现在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',

我的项目树状结构如下：

^{pr2}$

我使用python manage.py startapp idmp_core创建了idmp_core，而且很好。在

我修改了idmp_core目录的models.py。当我执行命令时

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
