CentOS安装PyQT5.11

yum install qt5-qtbase-devel
pip3 install pyqt5
python3 -c "from PyQt5 import QtWidgets"

CentOS安装PyQT5.6

一、安装CentOS7

1. 安装完成后进行更新
   sudo yum update -y
2. 增加epel 源
   yum install epel-release -y

二、 安装qt5

1. 安装qt5.6
   yum install qt5-qtquickcontrols qt5-qtdeclarative-devel -y

三、 安装PyQT5

1. 安装编译环境
   yum install gcc gcc-c++ python-devel -y

2. 下载sip-4.18
   wget http://nchc.dl.sourceforge.net/project/pyqt/sip/sip-4.18/sip-4.18.tar.gz

3. 装sip-4.18

   　　　sudo tar xzvf sip-4.18.tar.gz 　　 sudo cd sip 　　　sudo python configure.py 　　　sudo make 　　　sudo make install

4. 下载pyqt5.6
   wget http://nchc.dl.sourceforge.net/project/pyqt/PyQt5/PyQt-5.6/PyQt5_gpl-5.6.tar.gz

5. 安装qt5-qtbase-devel
   yum install qt5-qtbase-devel -y

6. 编译并安装 pyqt

   　　　sudo tar xzvf PyQt5_gpl-5.6.tar.gz 　　　sudo cd PyQt5_gpl-5.6 　　　sudo python configure.py --qmake=/usr/bin/qmake-qt5 　　　sudo make all 　　　sudo make install

tip:
　　1.步骤sudo python configure.py --qmake=/usr/bin/qmake-qt5会出错:
　　　　Error: This version of PyQt5 and the commercial version of Qt have incompatible licenses.
　    解决办法:
　　　　vi configure.py #大约在2681行，可根据关键字搜索
              修改红色标记处： if introspecting and target_config.qt_licensee not in 'Open Source' and ltype == 'GPL':

　　2. 步骤sudo make all 会出错：

　　　　error: 'WindowOkButtonHint' : is not a member of 'Qt'

error: 'WindowCancelButtonHint' : is not a member of 'Qt'

解决办法：根绝报错大约是在/root/PyQt5_gpl-5.6/QtCore/sipQtCoreQt.cpp 的1085和1098行，  删除这两行就好了
