从sqlite迁移至MySQL之后，seafile.sh可以正常启动，但是seahub.sh无法启动
报错如下：
LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub at port 8000 …
Error happened during creating seafile admin.
Exception AttributeError: “‘SyncClient’ object has no attribute ‘_connfd’” in <bound method SyncClient.del of <ccnet.sync_client.SyncClient object at 0x7fd7b8c05210>> ignored
Error:Seahub failed to start.
Please try to run “./seahub.sh start” again
本人对Python不懂，不知道此报错如何下手，求大神支招，十分感谢
PS:服务是部署在aws上面的。
