Ubuntu-Anaconda 2020.02-命名空间Gtk不可用 [英] Ubuntu - Anaconda 2020.02 - Namespace Gtk not available

问题描述

这是在Ubuntu 16.04 LTS上.

This is on Ubuntu 16.04 LTS.

我遇到了与此问题相同的问题:

I've run into the same issue as this question:

ValueError:命名空间Gtk不可用

我已经完成了以下操作来设置gtk3

I've done the following to set things up for gtk3

conda install -c conda-forge pygobject
sudo apt-get install libgtk-3-dev
sudo apt install python3-gi gobject-introspection gir1.2-gtk-3.0

但是，简单的测试程序位于:

However, the simple test program at:

https://python-gtk-3-tutorial .readthedocs.io/en/latest/introduction.html

失败，出现相同错误:

Python 3.7.7 (default, Mar 26 2020, 15:48:22) 
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>> gi.require_version("Gtk", "3.0")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/me/anaconda3/lib/python3.7/site-packages/gi/__init__.py", line 129, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Gtk not available

还有其他可以尝试的解决方案吗?

Any other solutions that might be tried?

这是全新安装的Anaconda(Anaconda3-2020.02-Linux-x86_64.sh)；安装后进行了conda更新-全部.但是我想知道可能是什么问题.

This was on a fresh install of Anaconda (Anaconda3-2020.02-Linux-x86_64.sh); did a conda update --all after installation. But am wondering what might be wrong.

推荐答案

conda-forge上有一个gtk3软件包:

There is a gtk3 package available on conda-forge:

conda install -c conda-forge gtk3
