Question

我已经尝试了好几个星期来解决我的部署设置问题。当debug = True时，Heroku应用程序运行良好，但是，当我将debug更改为= False时，总是会收到500服务器错误。我已经尝试过其他关于此问题的stackoverflow线程的所有建议，但似乎没有一个对我有用。如果您有任何建议，请告诉我。

Answer 2

希望这对某人有帮助。对我来说，问题是我的html模板中的“ /css/layout.css”中的正斜杠（我知道..我正撞在墙上）并注释掉该行：STATICFILES_STORAGE ='whitenoise.storage.CompressedManifestStaticFilesStorage在我的设置文件中。经过这两个更改，可以完美地工作。
