django ManifestStaticFilesStorage 500 错误

Question

django 1.11.6

python 3.5.2

我想使用django css缓存功能，但是会出现500错误。下面是我的代码。

settings.py

STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage'
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

templates

<!-- Favicons -->
{% load static %}
<link rel="icon" type="image/x-icon" href="{% static "favicon/favicon.ico" %}">
<link rel="apple-touch-icon" href="{% static "favicon/apple-touch-icon-precomposed.png" %}">

<!-- Bootstrap -->
<link href="{% static "css/bootstrap.min.css" %}" rel="stylesheet">
<link href="{% static "css/style.css" %}" rel="stylesheet">

python3 manage.py collectstatic
