在安装PALM界面时，提示缺少PyQt4组件，现给出其安装过程：

安装SIP

在https://sourceforge.net/projects/pyqt/files/sip/sip-4.19.12/sip-4.19.12.tar.gz/download?use_mirror=iweb&r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fpyqt%2Ffiles%2Fsip%2Fsip-4.19.12%2Fsip-4.19.12.tar.gz%2Fdownload%3Fuse_mirror%3Dautoselect&use_mirror=iweb 网站下载SIP，并执行如下命令：

sudo apt-get install python-dev 
tar xvf sip-4.19.12.tar.gz 
cd /home/annie/sip-4.19.12
sudo python configure.py
sudo make install

如果make命令执行时有error，Python.h 未找到错误，说明没有安装对应的Python版本的dev包，需键入以下命令：

sudo apt-get install python2.7-dev

注意要根据自己python的版本来安装相应的dev

下载安装Qt4依赖的库

sudo apt-get install qt4-dev-tools qt4-doc qt4-qtconfig qt4-demos qt4-designer libqwt5-qt4 libqwt5-qt4-dev 

安装PyQt4

从https://www.riverbankcomputing.com/software/pyqt/download下载压缩包 PyQt4_gpl_x11-4.12.1.tar.gz 解压

tar xvf PyQt4_gpl_x11-4.12.1.tar.gz 
cd /home/annie/PyQt4_gpl_x11-4.12.1
sudo python configure.py
sudo make
sudo make install

安装完成! 输入 palmrungui，显示如下：
