百度云盘linux客户端bcloud

1.Archlinux安装百度云盘linux客户端bcloudbcloud-x.x.x-any.pkg.tar.xz 从主页上下载（要注册成为会员）
请先从AUR上安装python-keyring, 然后使用pacman -U bcloud-x.x.x-any.pkg.tar.xz这个包
会出现这个问题：
ile "/usr/bin/bcloud-gui", line 9, in
from bcloud.App import App
File "/usr/lib/python3.4/site-packages/bcloud/App.py", line 21, in
import gutil
File "/usr/lib/python3.4/site-packages/bcloud/gutil.py", line 11, in
import dbus
ImportError: No module named 'dbus'
 只要安装 python-dbus就可以了
2.发现不能下载
3.作者说，是百度改了接口
4.下载3.3.7的deb包，解压缩
5.除了图标，把其它的按目录复制过去了，其中/home/qwer/usr/lib/python3/dist-packages/bcloud 复制到/home/qwer/save/usr/lib/python3.4/site-packages
6.问题：
Traceback (most recent call last):

7.pacman -S python-crypto
