hp-setup python3错误：无法导入名称“ _gobject”

我刚刚开始在Arch Linux上收到此错误。到目前为止，hp-setup一直运行良好。我不明白该错误信息。

hp设置

HP Linux Imaging and Printing System (ver. 3.17.11)

    from gi import _gobject as gobject
ImportError: cannot import name '_gobject'

看到此错误后，我重新安装了hplip（这是拥有hp-setup文件的软件包）。

pacman -Qo /usr/share/hplip/setup.py                                                                       
/usr/share/hplip/setup.py is owned by hplip 3.17.11-1

那没有解决问题。

该错误发生在没有命令行选项（默认为GUI模式）或--gui选项的情况下。但是，使用该--interactive选项（这是纯文本模式），我没有收到该错误。

另一台具有相同设置（就已安装的软件包和设置而言）的Arch计算机没有错误（即使在GUI模式下也是如此）。

更新1：
