将 Django 部署到 Heroku 会导致服务器错误 (500)

Question

请我知道这个问题已经被问过好几次了，但是有了这些答案我仍然没有解决它。我在我的 settings.py 文件中将 debug 设置为 False（但在我将其设置为 false 之前，一切正常），当我运行 git push heroku master 并访问我的网站，我收到一条错误消息，提示服务器错误（500）。 我需要帮助。

请这是我的settings.py

import os
import django_heroku 

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

SECRET_KEY = 'KEY'

DEBUG = False

ALLOWED_HOSTS = ['.herokuapp.com']

INSTALLED_APPS = [

ROOT_URLCONF = 'mysite.urls'

TEMPLATES = [

        },
    },
]

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

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

STATIC_URL = '/static/'




STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

django_heroku.settings(locals())

这是我的 wsgi.py

import os

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
application = get_wsgi_application()
application = DjangoWhiteNoise(application)]

这是我的过程文件

web: gunicorn mysite.wsgi

这里也是日志

Answer 1

WhiteNoise 主要是问题所在，因此，如果您对此不感兴趣，请禁用它：

STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
django_heroku.settings(locals())

至（按此顺序）：

django_heroku.settings(locals())
STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.StaticFilesStorage'

也删除

application = DjangoWhiteNoise(application)]
