Cannot use terminal client on Debian 10 on RPi

Following official installation instructions, apt installation successful but when using it such as

seaf-cli status

shows error message

Traceback (most recent call last):
  File "/usr/bin/seaf-cli", line 99, in <module>
    import seafile
  File "/usr/lib/python2.7/dist-packages/seafile/", line 2, in <module>
    from rpcclient import SeafileRpcClient as RpcClient
  File "/usr/lib/python2.7/dist-packages/seafile/", line 1, in <module>
    from pysearpc import searpc_func, SearpcError, NamedPipeClient
ImportError: No module named pysearpc

Closer inspection shows that I’ve installed it with python 2. But in the official instruction page it says " note: from seafile version 7.0.8, seaf-cli only support python3.5 or above on Debian/Ubuntu."

When I get into python 3 and import pysearpc there’s no problem. So how do I install seafile-cli with python 3? Or is it even where the problem is?

Thank you!

Looks like there’s no binary for arm yet, so I need to build it myself or wait.
