【问题描述】：

settings.py

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

ALLOWED_HOSTS = ['my-app.herokuapp.com', '127.0.0.1:8000', 'localhost']

django_heroku.settings(locals())

STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
STATIC_URL = '/static/'

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'build/assets')
]

错误（2 个例外）

remote: Traceback (most recent call last):
remote:   File "/app/.heroku/python/lib/python3.9/site-packages/django_heroku/core.py", line 97, in settings
remote:     config['MIDDLEWARE_CLASSES'] = tuple(['whitenoise.middleware.WhiteNoiseMiddleware'] + list(config['MIDDLEWARE_CLASSES']))
remote: KeyError: 'MIDDLEWARE_CLASSES'

remote:     django_heroku.settings(locals())
remote:   File "/app/.heroku/python/lib/python3.9/site-packages/django_heroku/core.py", line 99, in settings
remote:     config['MIDDLEWARE'] = tuple(['whitenoise.middleware.WhiteNoiseMiddleware'] + list(config['MIDDLEWARE']))

我正在尝试部署我的网络应用程序，但每次都遇到此错误，无法在任何地方找到解决方案... Procfile、requirements.txt 和 runtime.txt 没有任何问题，感谢任何帮助！

【问题讨论】：

运行collect static时会出现吗？

不，我禁用了它。

【参考方案1】：

没关系，我修复了它，在我的文件中 django_heroku.settings(locals()) 是 above 中间件列表，因此导致错误...现在我遇到了 app.settings 所在的问题没找到，猜猜另一个问题是不可避免的。
