我在Ubuntu 18.04上安装了石墨，但遇到以下问题：
我做到了： -权限：
chown -R www-data:www-data /usr/share/graphite-web/
chmod +x /usr/share/graphite-web/graphite.wsgi
import sys
# In case of multi-instance graphite, uncomment and set appropriate name
# import os
# os.environ['GRAPHITE_SETTINGS_MODULE'] = 'graphite.local_settings'
sys.path.append('/opt/graphite/webapp')
from graphite.wsgi import application
Bu仍然是同一问题：
