Python Django应用程序部署到Heroku，应用程序错误，

我正在努力将我的Django 1.10应用程序部署到Heroku。作为前言，我正在使用Pycharm，曾一度不得不重命名我的项目，但它在所有地方都进行了重构并更改了名称，所以我希望这与问题无关。当我把这个网站推到Heroku时，我得到一个应用程序错误

错误消息

在Heroku应用程序错误日志中，我看到：

2017-01-13T22:04:48.911324+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=secret-anchorage-68558.herokuapp.com request_id=71351a21-2264-4ca7-ad0a-1ae110d72ca7 fwd="162.247.89.174" dyno= connect= service= status=503 bytes=

它曾经在我的计算机上本地工作，但现在当我尝试运行应用程序时，我得到：

python3 manage.py runserver

ImportError: No module named 'homelibrary.apps'

这似乎很有希望。它允许我将代码推送到Heroku，但是当我尝试

heroku run python3 manage.py migrate

或

我得到了和以前一样的错误，它不会出现在网上

你知道我做错了什么吗？

只要用这个更改你的

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',
    'catalog',
]

之后你会面临更多的错误

如果生产中的

DEBUG

设置为

False

，则需要更改

ALLOWED\u HOSTS=[]

到

允许的\u主机=['*']

加载项

settings.py

文件

STATICFILES\u STORAGE='whitenoise.django.gzip静态文件存储'

---

如果它不起作用，那么再做一件事，看看第8步和第9步

谢谢，这对解决静态文件问题很有帮助。我有一个类似的问题，但这里的解决方案对我来说并不适用。你能帮我看看吗？
