seahub_settings.py 配置文件内容如下:

-- coding: utf-8 --

SECRET_KEY = “^%u%z9-%1=f4f=og#net7i_fujw90z&0@^ip8h#hrdaf=3_v@2”

ENABLE_THUMBNAIL = True

THUMBNAIL_IMAGE_SIZE_LIMIT = 30

THUMBNAIL_ROOT = ‘/usr/local/seafile/seahub-data/thumbnail/thumb/’

ENABLE_VIDEO_THUMBNAIL = True

THUMBNAIL_VIDEO_FRAME_TIME = 5

THUMBNAIL_SIZE_FOR_ORIGINAL = 1024

请问各位大神这该如何解决?
