#1 Python3.5
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.5
#2 Qt5
wget http://mirror.bit.edu.cn/qtproject/official_releases/qt/5.5/5.5.1/qt-opensource-linux-x64-5.5.1.run
chmod a+x qt-opensource-linux-x64-5.5.1.run
sudo ./qt-opensource-linux-x64-5.5.1.run
sudo ln -s /opt/Qt5.5.1/5.5/gcc_64/bin/qmake /usr/bin/
安装完成后配置一下PATH，在当前用户主目录下的.bashrc （or .zshrc）文件中加入：
export QTDIR=/opt/Qt5.5.1/5.5/gcc_64/
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}${QTDIR}lib
export PATH=${QTDIR}bin:${PATH}
export QT_QPA_PLATFORM_PLUGIN_PATH=${QTDIR}plugins/
#3 SIP
下载：http://www.riverbankcomputing.com/software/sip/download
tar xvf sip-4.16.4.tar.gzcd sip-4.16.4
python3 configure.py
make
sudo make install
#4 PyQt5
下载：http://www.riverbankcomputing.com/software/pyqt/download5
tar xvf PyQt-gpl-5.3.2.tar.gz
cd PyQt-gpl-5.3.2
python3 configure.py
注意：此命令生成各种Qt模块后，其中的QtWebKitWidgets模块由于Qt4和Qt5的qprinter.h所属模块的调整（Qt4存在于 QtGui中，Qt5将其调整到QtPrintSupport中了），QtWebKitWidgets的Makefile中缺失了对 QtPrintSupport的头文件目录引用，会导致后面编译PyQt5时无法找到qprinter.h头文件，编译失败（编译过程非常漫长）：qprinter.h: No such file or directory
解决方案:在 /opt/Qt5.5.1/5.5/gcc_64/include/QtPositioning/ 和 /opt/Qt5.5.1/5.5/Src/qtlocation/include/QtPositioning/ 以及目录中放置qgeolocation.h文件
wget https://raw.githubusercontent.com/RSATom/Qt/master/qtlocation/src/positioning/qgeolocation.h
sudo cp qgeolocation.h /opt/Qt5.5.1/5.5/gcc_64/include/QtPositioning/
sudo mkdir -p /opt/Qt5.5.1/5.5/Src/qtlocation/include/QtPositioning/
sudo cp qgeolocation.h /opt/Qt5.5.1/5.5/Src/qtlocation/include/QtPositioning/
编译
make
sudo make install
安装完成后进入Python3环境验证是否安装成功：
python3
>>> from PyQt5.QtCore import PYQT_VERSION_STR
>>> print(PYQT_VERSION_STR)
