Heroku没有检测静态文件的Django设置

Question

我正在创建一个项目，我想部署在Heroku上。我们正在使用Django，并希望保持我们对Heroku的静力学，因为它是一个小应用程序。

我遇到的问题是，当Heroku运行python manage.py collectstatic --noinput时，我会遇到一个错误，说明我没有设置STATIC_ROOT。我的文件结构如下：

├── htmlcov
├── mysite
│   ├── settings.py
│   ├── wsgi.py
│   ├── urls.py
│   └── random.py
│
├── staticfiles
├── tweetmood
│   ├── migrations
│   └── tests
│
├── Procfile
├── runtime.txt
└── manage.py

我的设置文件是

Procfile：

在本地，heroku local和heroku local web都工作得很好。但是，即使python manage.py collectstatic --noinput运行，每次也会创建更多的文件。然而，每当我试图推到Heroku时，我都会得到以下错误消息

raise ImproperlyConfigured("You're using the staticfiles app "
        django.core.exceptions.ImproperlyConfigured: You're using the staticfiles app without having set the STATIC_ROOT setting to a filesystem path.

  !     Error while running '$ python manage.py collectstatic --noinput'.
        See traceback above for details.

        You may need to update application code to resolve this error.
        Or, you can disable collectstatic for this application:

           $ heroku config:set DISABLE_COLLECTSTATIC=1

        https://devcenter.heroku.com/articles/django-assets

 ****** Collectstatic environment variables:ttps://devcenter.heroku.com/articles/django-assets

然后打印一组不包括BASE_DIR、STATIC_ROOT或STATIC_URL的环境变量。我怀疑这是我的问题的根本原因，但我不知道如何解决它。

我正在寻找一种方式来增加静力学，以便我可以部署和仍然有这些资源可供我使用。

Answer 1

原来，当我推到Heroku时，我推错了分支，而在本地的正确分支上，为了将正确的分支推到heroku远程，您必须使用git push heroku yourbranch:master。

当我通过命令行访问heroku之后，我终于发现了这一点，并查看了我的代码，发现了其中的区别。确保使用正确的分支。

Answer 2

在我的例子中，问题是在执行git push heroku之前，我并没有实际地对settings.py进行更改。
