出現該問題的原因：
django沒有在setting.py的配置文件中找到app內容，需要增加app的名稱
1 E:\PycharmProjects\Mysite>python manage.py makemigrations 2 No changes detected 3 4 E:\PycharmProjects\Mysite>python manage.py makemigrations blog 5 App 'blog' could not be found. Is it in INSTALLED_APPS?
setting.py 中並未有blog項目的名稱
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ]
增加后的即可解決上述問題
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'blog' ] ===============可運行命令成功===================== E:\PycharmProjects\Mysite>python manage.py makemigrations Migrations for 'blog': blog\migrations\0001_initial.py - Create model UserInfo
