hp-setup python3 錯誤：無法導入名稱“_gobject”

我剛開始在 Arch Linux 上遇到這個錯誤。到目前為止，hp-setup 一直執行良好。我不明白錯誤資訊。

惠普設置

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'

看到這個錯誤後，我重新安裝了 hplip（它是擁有 hp-setup 文件的軟體包）。

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

那並沒有解決問題。

錯誤發生在沒有命令行選項（預設為 GUI 模式）或--gui選項的情況下。但是，使用該--interactive選項（這是純文字模式），我沒有收到錯誤消息。

另一台具有相同設置（就安裝的軟體包和設置而言）的 Arch 電腦沒有錯誤（即使在 GUI 模式下）。

更新1：

$ pacman -Qi hplip

解決方案很簡單：

pacman -S --needed python-gobject

確實需要安裝它。

報告pacman -Qi hplip指出：

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

具有誤導性。當我執行時，pacman -Qi python-gobject我發現它實際上並沒有安裝。安裝它解決了這個問題。
