按照说明2.入门——Python GTK+ 3 教程 3.4 文档进行操作。
尝试。
In [6]: import gi
...: gi.require_version('Gtk', '3.0')
...: from gi.repository import Gtk
IT报告错误：
~/anaconda3/lib/python3.7/site-packages/gi/__init__.py in require_version(namespace, version)
128 available_versions = repository.enumerate_versions(namespace)
129 if not available_versions:
--> 130 raise ValueError('Namespace %s not available' % namespace)
131
132 if version not in available_versions:
ValueError: Namespace Gtk not available
请跟随如何在Ubuntu上安装GTK+ 3.0? - Ask Ubuntu并将Gtk安装到Ubuntu。
sudo apt-get install libgtk-3-dev
然而，它仍然报告相同的错误。
我该如何解决这个问题？

我在安装Dropbox到Ubuntu时遇到了问题

Run "dropbox start -i" to install the daemon
运行"dropbox start -i"

gi.require_version('Gtk', '4.0')。我猜测 GTK 4.0 已经发布并正在广告宣传中，但 Ubuntu 20.04 只有 GTK 3.0。例如，请参考 https://askubuntu.com/questions/1304261/how-to-get-gtk4-in-ubuntu-20-04。 - nealmcb
