尝试迁移文件后出现此错误
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)

        "duplicates: %s" % app_config.label)
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: auth

请帮忙。

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'
 ]
