我试图在Django中创建一个自定义用户模型，但是它给了我很多错误

Question

我正在开发一个Django项目，所以我有了调度应用程序，应用程序上的真正功能，我创建了一个“帐户”应用程序来修改基本用户模型，这样我就可以让用户用他的/她的电子邮件登录。如果你能帮我解决这个问题，我会非常感激，因为我有点困了。 但是，现在我修改了型号.py（在“帐户”应用程序中）并修改设置.py在主网站文件夹中，我收到以下错误（最后一个错误包括安装的应用程序设置错误，我不明白）：

Traceback (most recent call last): File "C:/PythonProjects/tutorTrip/manage.py", line 15, in execute_from_command_line(sys.argv) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\core\management__init__.py", line 371, in execute_from_command_line utility.execute() File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\core\management__init__.py", line 365, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\core\management\base.py", line 288, in run_from_argv self.execute(*args, **cmd_options) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\core\management\commands\runserver.py", line 61, in execute super().execute(*args, **options) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\core\management\base.py", line 335, in execute output = self.handle(*args, **options) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\core\management\commands\runserver.py", line 70, in handle if not settings.DEBUG and not settings.ALLOWED_HOSTS: File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\conf__init__.py", line 56, in getattr self._setup(name) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\conf__init__.py", line 43, in _setup self._wrapped = Settings(settings_module) File "C:\Users\Alienware\AppData\Local\Programs\Python\Python36\lib\site-packages\django\conf__init__.py", line 120, in init raise ImproperlyConfigured("The %s setting must be a list or a tuple.

从Django DOC - ^{}

A list of strings designating all applications that are enabled in this Django installation. Which says

但是，您将INSTALLED_APPS定义为集对象（{}）。{}语法用于表示集合对象

因此，将INSTALLED_APPS更改为如下所示

INSTALLED_APPS = [
    ..... # your apps
      ]

示例

In [1]: a = {1,3}

In [2]: b= [1,3]

In [3]: c = (1,3)

In [4]: type(a)
Out[4]: set

In [5]: type(b)
Out[5]: list

In [6]: type(c)
Out[6]: tuple
