静态文件配置不正确

我已经在 Heroku 上部署了简单的博客应用程序，它运行在Django=1.8.4，我在静态文件方面遇到了一些问题。

当打开我的应用程序时，我看到Application Error页面，所以我尝试调试它并发现当我提交到 Heroku 时它无法在我的静态文件夹上执行collectstatic。其他一切都正常，Heroku 向我展示了这一点Build succeeded但无法执行

remote: -----> Preparing static assets
remote:        Collectstatic configuration error. To debug, run:
remote:        $ heroku run python bloggy_project/manage.py collectstatic --noinput

所以 Heroku 希望我调试它。我输入后

heroku run python bloggy_project/manage.py collectstatic --noinput

错误日志显示：

Running python bloggy_project/manage.py collectstatic --noinput on greenbloggy... up, run.4682

    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.

尝试用谷歌搜索答案，我现在很困惑，因为我读过很多关于静态文件的帖子。有人可以告诉我这里出了什么问题吗，这样我就可以学习和理解一些东西。

UPDATE:

当我评论出来的时候STATIC_ROOT，并做

heroku run python bloggy_project/manage.py collectstatic --noinput

现在显示错误日志，这部分令人困惑，为什么现在出现这个错误，如果我需要把STATIC_ROOT在我的settings.py?

您收到此错误是因为您的设置变量STATIC_ROOT and STATICFILES_DIRS包含完全相同的路径（os.path.join(BASE_DIR, 'static')）。这是无效的配置。

STATIC_ROOT是您希望 Django 放置使用收集的静态文件的绝对路径collectstatic。您的网络服务器将从该目录提供静态文件。

STATICFILES_DIRS是您想要的目录列表collectstatic收集静态文件时查看。如果不能包括STATIC_ROOT或其任何子目录。

尝试删除STATICFILES_DIRS设置并看看是否有效。如果您已将静态文件放在某个非标准位置，则更改设置以包含该位置。
