Django Heroku服务器错误（500），当我将Debug-False设置为True时，它工作正常

我知道这方面有很多问题，但老实说，大多数问题都没有答案，或者解决方案不起作用

我有个“简单”的问题。当我将Debug设置为False并将其推送到heroku时，我会得到“Server Error（500）”。我读了这些主题：

我尝试了他们的解决方案，但仍然不起作用。唯一的解决方案，我没有测试，应该是帮助摆脱白噪声。这个对我来说有点“不行”

对此错误我能做些什么

谢谢，干杯

编辑：

这是我的日志。我试着把白噪音注释掉，但没用

我在查看我的代码，但我没有提到“favicon.ico”。另外，我尝试运行collectstatic，因为我发现了一些与此相关的主题，但它对我不起作用

首先它问我：

You have requested to collect static files at the destination
location as specified in your settings:

    /app/staticfiles

然后我得到了一个错误：

FileNotFoundError: [Errno 2] No such file or directory: '/app/static'

这很奇怪，因为首先它向我证实了我将这个文件夹从静态文件过度引用到了静态文件。在我的主目录中有一个文件夹“staticfiles”。在我的应用程序文件夹中，我有“静态”文件夹。关闭调试后，一切正常

我想我明白了。解决方案正在发挥作用。但我觉得这也很奇怪。如果有人能评论一下为什么会这样，我将不胜感激

您可以离开whitenoise，您可以稍微整理一下静态文件dirs。让它看起来像这样：

STATIC_URL = '/static/'
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')


STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

但我认为这没有必要。（最好将“静态”文件夹保存在主项目文件夹中）

但最大的问题是（在django 3上工作）：

你需要跑步

python manage.py collectstatic

本地的！然后交给希罗库。然后，调试设置为False时，一切正常。我试着保持静态。保持文件。我尝试只提交.json，希望它能重新填充新的静态文件。但不行。只有在本地运行collectstatic，然后将所有内容提交给heroku时，它才起作用

如果有人对这个问题有更多的了解，并能向我解释，我将非常感激

同时，我希望其他人也能从这个解决方案中受益

我找到了这个问题的答案-。非常感谢emazzotta，我也不必摆脱whitenoise，它在django3工作。

在不使用whitenoise的情况下尝试一次，看看是否会导致问题。我尝试注释掉whitenoise，但没有帮助，我在编辑的帖子中添加了我的日志。请编辑你的帖子，使其包含静态设置。还请显示你的目录结构以及什么是
static\u TMP=os.path.join（BASE\u DIR，'static'）
？如果您的
staticfiles/
