无法启动 cinnamon-settings vluetooth 模块

Question

单击 cinnamon-settins 中的蓝牙时出现此错误：

Traceback (most recent call last):
  File "/usr/lib/blueberry/blueberry.py", line 5, in <module>
    import rfkillMagic
  File "/usr/lib/blueberry/rfkillMagic.py", line 5, in <module>
    from gi.repository import GLib
ModuleNotFoundError: No module named 'gi'

我能做些什么？？？
