我在尝试迁移文件后遇到此错误

PS C:\djangoproject\src> python manage.py makemigrations

Traceback (most recent call last): 
  File "manage.py", line 15, in <module>
execute_from_command_line(sys.argv)

     apps.populate(settings.INSTALLED_APPS)   
  File "C:\Program Files\Python36\lib\site-packages\django\apps\registry.py", line 93, in populate
        "duplicates: %s" % app_config.label)
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: auth

请帮忙。

看起来像您自定义的身份验证应用程序。换个名字就行了
INSTALLED_APPS = ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages' , 'django.contrib.staticfiles', 'profiles', 'crispy_forms', 'django.contrib.auth', 'django.contrib.sites', 'allauth', 'allauth.account', ]
从 django.apps 导入 AppConfig 类 ProfilesConfig(AppConfig): name = 'profiles' verbose_name = 'myprofile'
default_app_config = 'profiles.apps.ProfilesConfig'
urlpatterns = [ path('', views.index, name='index'), path('about/', views.about, name='about'), path('contact/ ', views.contact, name='contact'), path('admin/', admin.site.urls), path('accounts/', allauth.urls), ]

标签： python django django-admin django-authentication django-allauth

【解决方案1】：

你有一个额外的'django.contrib.auth'

INSTALLED_APPS = [ 'django.contrib.admin', 
               'django.contrib.auth', 
               'django.contrib.contenttypes', 
               'django.contrib.sessions', 
               'django.contrib.messages', 
               'django.contrib.staticfiles', 
               'profiles', 
               'crispy_forms', 
               'django.contrib.auth',     --->EXTRA Remove this
               'django.contrib.sites', 
               'allauth', 
               'allauth.account'
 ]

urlpatterns = [ path('', views.index, name='index'), path('about/', views.about, name='about'), path('contact/ ', views.contact, name='contact'), path('admin/', admin.site.urls), path('accounts/', include('allauth.urls')), ]
文件 "C:\djangoproject\src\testsite\urls.py"，第 28 行，在 path('accounts/', include('allauth.urls'))，NameError：名称“包含”未定义
urlpatterns = [ path('', views.index, name='index'), path('about/', views.about, name='about'), path('contact/ ', views.contact, name='contact'), path('admin/', admin.site.urls), path('accounts/', allauth.urls), ]
