我是Django的新手，这是我第一次尝试在WebFaction上部署Django应用程序。 我在StackOverflow上进行了搜索，但没有找到遇到相同问题的人。
我的应用是使用Django 2.2和Python 3.7.3开发的。 我已成功运行makemigrations ， migrate ， collectstatic我的电脑上的本地主机和Windows上获得到SSH服务器WebFaction使用腻子时成功运行这些命令。
但是，当我重新启动WebFaction服务器并使用浏览器访问时，它返回了ModuleNotFoundError 。
ModuleNotFoundError at /
No module named 'app_www_admission.urls'
Request Method: GET
Request URL: (my website's URL)
Django Version: 2.1.7
Exception Type: ModuleNotFoundError
Exception Value:
No module named 'app_www_admission.urls'
Exception Location: <frozen importlib._bootstrap> in _find_and_load_unlocked, line 965
Python Executable: /usr/local/bin/python3
Python Version: 3.7.3

我尝试解析我在以下文件中导入的软件包： admin.py ， forms.py ， models.py ， settings.py ，main urls.py ，应用程序的urls.py ， views.py ，我意识到：
为了进行开发，我必须使用以下命令导入：
from app_www_admission.models import ...
为了生产，当我重新启动Webfaction服务器时，必须使用以下命令导入：
from app_www_admission.app_www_admission.models import ...
选项（1）让我运行makemigrations ， migrate ， collectstatic ， check的命令等，但通过浏览器访问该网站时，正如我上面提到导致ModuleNotFoundError。 服务器的错误日志如下。
选项（2）让我通过浏览器访问的网站如我所料（在浏览器中没有更多的ModuleNotFoundError），但我不能命令做任何事情makemigrations ， migrate ， collectstatic ， check等，因为它总是抛出
ModuleNotFoundError: No module named 'app_www_admission.app_www_admission' 。
有关更多信息，我通过将所有文件从本地计算机复制到WebFaction，已安装的pip和必要的程序包进行部署，但问题似乎出在app_www_admission上 。 现在我可以做的是：切换到（1），运行所有必需的命令（以进行迁移或执行某些操作），然后通过编辑服务器上的所有相关文件切换到（2），然后重新启动服务器。 在这些选项之间进行切换非常麻烦，我知道在某个地方我一定很傻并且错了。
您能告诉我我提到的导入路径有什么问题吗？设置或某些方面有什么问题吗？ 非常感谢您的帮助。
