python - 如何在虚拟环境中安装python "gi"模块？

Question

我看过this ，并尝试了以下代码:

ln -s /usr/lib/python2.7/dist-packages/pygtk.pth tools/python_2_7_9/lib/python2.7/site-packages/
ln -s /usr/lib/python2.7/dist-packages/gobject tools/python_2_7_9/lib/python2.7/site-packages/
ln -s /usr/lib/python2.7/dist-packages/gtk-2.0 tools/python_2_7_9/lib/python2.7/site-packages/
ln -s /usr/lib/python2.7/dist-packages/pygtk.pth tools/python_2_7_9/lib/python2.7/site-packages/
ln -s /usr/lib/python2.7/dist-packages/glib tools/python_2_7_9/lib/python2.7/site-packages/
ln -s /usr/lib/python2.7/dist-packages/gi tools/python_2_7_9/lib/python2.7/site-packages/
ln -s /usr/lib/python2.7/dist-packages/pygtkcompat tools/python_2_7_9/lib/python2.7/site-packages/

，但是import glib 或import gi 仍然会产生错误:

yba@ubuntu:~/Documents/XXX/tools$ source python_2_7_9/bin/activate
(python_2_7_9) yba@ubuntu:~/Documents/XXX/tools$ python
Python 2.7.9 (default, Aug 29 2016, 16:04:36)

>>> import glib

    from glib._glib import *
ImportError: /home/yba/Documents/XXX/tools/python_2_7_9/lib/python2.7/dist-packages/glib/_glib.so: undefined symbol: PyUnicodeUCS4_DecodeUTF8

ImportError: /home/yba/Documents/lucida/tools/python_2_7_9/lib/python2.7/dist-packages/gi/_gi.so: undefined symbol: PyUnicodeUCS4_FromUnicode
>>> 

与该帖子类似，系统范围的 python 工作正常:

yba@ubuntu:~$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>> import glib
>>> 

如何解决这个问题？另外，我真正需要的是 import gi.repository 而不是 import gi。非常感谢!

现在可以使用 vext 来解决这个问题. Vext 允许您在单独访问系统包的 virtualenv 中安装包。要访问 gi，请执行以下操作:

pip install vext
pip install vext.gi
