CentOS7.1下python2.7.10安装PyQt4

新人肯定跟我一样,那就是plt.show()在Linux环境下不显示,后来才明白,这是matplotlib依赖图形环境,有兴趣的可以去了解下matplotlib后端(Backend )相关知识.下面安装PyQt4解决.

1.安装sip

[root@p168 ~]# wget http://downloads.sourceforge.net/project/pyqt/sip/sip-4.17/sip-4.17.tar.gz
[root@p168 ~]# tar xvf sip-4.17.tar.gz

[root@p168 ~]# cd sip-4.17

[root@p168 sip-4.17]# python configure.py

[root@p168 sip-4.17]# make & make install & make clean

2.通过安装qscintilla安装qt

[root@p168 ~]#yum -y install epel-release

[root@p168 ~]#yum install qscintilla*

3.安装pyqt4

[root@p168 ~]# wget http://downloads.sourceforge.net/project/pyqt/PyQt4/PyQt-4.11.4/PyQt-x11-gpl-4.11.4.tar.gz
[root@p168 ~]# tar xvf PyQt-x11-gpl-4.11.4.tar.gz

[root@p168 ~]# cd PyQt-x11-gpl-4.11.4

[root@p168 PyQt-x11-gpl-4.11.4]# python configure.py -q /usr/lib64/qt4/bin/qmake

[root@p168 PyQt-x11-gpl-4.11.4]# make & make install & make clean

4.测试

[root@p168 PyQt-x11-gpl-4.11.4]# python
