Python 如何解决运行Django服务器时出现的重复应用程序问题

我创建了一个名为

session\u booker

的Django应用程序，并添加了一个名为

sessions

的应用程序。当我尝试运行Django服务器时，出现以下错误：

$ python manage.py migrate
Traceback (most recent call last):
  File "manage.py", line 21, in <module>
    main()
  File "manage.py", line 17, in main
    execute_from_command_line(sys.argv)
  File "/Users/me/.local/share/virtualenvs/SessionBooker-fBhCDalc/lib/python3.8/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line
    utility.execute()
  File "/Users/me/.local/share/virtualenvs/SessionBooker-fBhCDalc/lib/python3.8/site-packages/django/core/management/__init__.py", line 377, in execute
    django.setup()
  File "/Users/me/.local/share/virtualenvs/SessionBooker-fBhCDalc/lib/python3.8/site-packages/django/__init__.py", line 24, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/Users/me/.local/share/virtualenvs/SessionBooker-fBhCDalc/lib/python3.8/site-packages/django/apps/registry.py", line 93, in populate
    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: sessions

名称会话干扰了他内置的

    'django.contrib.sessions',

因此，在您的情况下，请将应用程序的名称更改为其他名称

请从您的设置中添加已安装的应用程序。pyNow添加到问题。添加了答案；试试这个，告诉我这是否对你有用是的，就是这样。谢谢你的帮助。很高兴有帮助：）
