如何解决运行Django服务器时出现的重复应用程序问题

Question

我创建了一个名为session_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

我甚至不知道从哪里开始。我猜我在不知不觉中创建了两个应用程序。如果是这样的话，有没有什么地方我可以删除一个？有人能告诉我怎么解决这个问题吗

这是我安装的应用程序：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'sessions.apps.SessionsConfig',
]

Answer 1

名称会话干扰了他内置的

    'django.contrib.sessions',

因此，在您的情况下，将应用程序的名称更改为其他名称
