Cannot start seaf-cli on fedora



i’d like to sync some libraries by command line tool, but only get the following error:
raceback (most recent call last):
File “/usr/bin/seaf-cli”, line 99, in
import seafile
File “/usr/lib64/python2.7/site-packages/seafile/”, line 2, in
from rpcclient import SeafileRpcClient as RpcClient
File “/usr/lib64/python2.7/site-packages/seafile/”, line 1, in
from pysearpc import searpc_func, SearpcError, NamedPipeClient
ImportError: cannot import name NamedPipeClient

i’m running fedora 29 (and 30beta) and i’m using the rpms of the distribution.

any hint what package/module i’m missing???
