在python 3.5（anaconda）和centos 7上使用GTKAgg后端

我尝试使用GTKAgg作为

matplotlib

包的后端

matplotlib.use('GTKAgg')
Failed to enable GUI event loop integration for 'gtk'
Traceback (most recent call last):

    module = self._system_import(name, *args, **kwargs)
ImportError: No module named 'gtk'

当我试图使用

pip

安装

pygtk

时，我遇到了这个错误

[oshri@analytics ~]$ pip install pygtk 
Collecting pygtk
  Using cached pygtk-2.24.0.tar.bz2
    Complete output from command python setup.py egg_info:
    ********************************************************************
    * Building PyGTK using distutils is only supported on windows. *
    * To build PyGTK in a supported way, read the INSTALL file.    *
    ********************************************************************

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-x78h7u1k/pygtk/

当我尝试使用

python2.7

时，我成功地导入了模型

[oshri@analytics ~]$ /bin/python2.7
Python 2.7.5 (default, Nov  6 2016, 00:28:07) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pygtk 
>>> exit()

因此，我认为问题与python版本有关。 我试图使用这个，但没有成功使用

我是对的，与python版本相关的问题

我应该在

root

user下安装

JHBuild

---

请注意，您必须使用

pip3

在python3下安装

pip

（或者可能是

pip2

）将使用默认的python进行安装，在大多数系统中仍然是python 2.7.x。我从未需要jhbuild在python下安装任何模块。这是我的pip版本

[oshri@analytics~]$pip——来自/data/anaconda/lib/python3.5/site-packages（python 3.5）的版本pip 9.0.1

在这种情况下，您总是为python 3.5安装软件包（除非我大错特错）。如果您使用的是3.5，我非常建议您使用内省（从gi.repository import gtk导入gtk时使用

——注意gtk中的G）。我甚至认为pygtk不适用于Python3.5。无论如何，自省是未来的方向。
