hp-setup python3 错误：无法导入名称“_gobject”

我刚开始在 Arch Linux 上遇到这个错误。 hp-setup 到目前为止一直运行良好。我不明白错误消息。

hp 设置

HP Linux Imaging and Printing System (ver. 3.17.11)
Printer/Fax Setup Utility ver. 9.0

    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

这并没有解决问题。

如果没有命令行选项（默认为 GUI 模式）或有--gui选项，则会发生该错误。但是，使用该--interactive选项（纯文本模式），我没有收到错误消息。

另一台具有相同设置（就安装的软件包和设置而言）的 Arch 计算机没有出现错误（即使使用 GUI 模式）。

答案1

解决方案很简单：

pacman -S --needed python-gobject

确实需要安装它。

报告pacman -Qi hplip指出：

python-gobject: for running hp-toolbox [installed]

具有误导性。当我运行时，pacman -Qi python-gobject我发现它实际上没有安装。安装它解决了这个问题。
