In the settings.py I am including the apps like this在 settings.py 中，我包含了这样的应用程序
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'whitenoise.runserver_nostatic',
'rest_framework',
'leads',
'frontend',
'knox',
'accounts'
]
I will attach an image of my folder structure我将附上我的文件夹结构的图像
this is working fine in my localhost but when ran on the heroku server with gunicorn results in this "Module not found error"这在我的本地主机上运行良好，但是当在带有 gunicorn 的 heroku 服务器上运行时会导致此“未找到模块错误”
Sorry I am new to django and was not able to find a solution for this issue抱歉，我是 Django 的新手，无法找到解决此问题的方法
