如何修复 Ubuntu 上的 Python 'ValueError: Namespace GnomeDesktop not available'

问题：

在 Ubuntu 上，你正在尝试使用 gi 包和 GnomeDesktop 运行 Python 脚本，但你看到此堆栈跟踪：

error.txt

Traceback (most recent call last):
  File "myscript.py", line 48, in <module>
    gi.require_version('GnomeDesktop', '3.0')
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 130, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace GnomeDesktop not available

    raise ValueError('Namespace %s not available' % namespace)

解决方案

安装 gir1.2-gnomedesktop-3.0：

sudo apt -y install gir1.2-gnomedesktop-3.0

sudo apt -y install gir1.2-gnomedesktop-3.0

然后重试运行你的脚本。
