我是 Django 的新手，我正在嘗試創(chuàng)建一個(gè)超級(jí)用戶（我在 Linux mint 上），每次我遇到一個(gè)非常奇怪的錯(cuò)誤，這是我在其他 Django 項(xiàng)目中沒(méi)有遇到的。錯(cuò)誤如下：（除了在已安裝的應(yīng)用程序列表中添加我的應(yīng)用程序和在 urls 中應(yīng)用程序的 url 之外，我沒(méi)有修改 django 項(xiàng)目中的任何內(nèi)容。）  File "/home/user/.local/lib/python3.6/site-packages/django/urls/resolvers.py", line 538, in url_patterns    iter(patterns)TypeError: 'module' object is not iterableDuring handling of the above exception, another exception occurred: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 "/home/user/.local/lib/python3.6/site-packages/django/core/management/__init__.py", line 371, in execute_from_command_line    utility.execute()  File "/home/user/.local/lib/python3.6/site-packages/django/core/management/__init__.py", line 365, in execute    self.fetch_command(subcommand).run_from_argv(self.argv)  File "/home/user/.local/lib/python3.6/site-packages/django/core/management/base.py", line 288, in run_from_argv    self.execute(*args, **cmd_options)  File "/home/user/.local/lib/python3.6/site-packages/django/contrib/auth/management/commands/createsuperuser.py", line 59, in execute    return super().execute(*args, **options)  File "/home/user/.local/lib/python3.6/site-packages/django/core/management/base.py", line 332, in execute    self.check()  File "/home/user/.local/lib/python3.6/site-packages/django/core/management/base.py", line 364, in check    include_deployment_checks=include_deployment_checks,  File "/home/user/.local/lib/python3.6/site-packages/django/core/management/base.py", line 351, in _run_checks    return checks.run_checks(**kwargs)  File "/home/user/.local/lib/python3.6/site-packages/django/core/checks/registry.py", line 73, in run_checks    new_errors = check(app_configs=app_configs)你能告訴我我在做什么錯(cuò)嗎？我嘗試創(chuàng)建一個(gè)虛擬環(huán)境，但它不起作用。
