Ubuntu 14 configure and install pyqt4 and pyqt5

1. Install pyqt4

We recommend that you use apt-get to install pyqt4.

sudo apt-get install libxext6 libxext-dev libqt4-dev libqt4-gui libqt4-sql qt4-dev-tools qt4-doc qt4-designer qt4-qtconfig "python-qt4-*" python-qt4

Very simple. It mainly records pyqt5 in the python3 environment.

2. Install pyqt5

2.1.python sip install

First download the SIP

tar -xvf sip*.tar.gz python configure.py make  sudo make install

2.2 install qt5

Here is the source download, http://www.riverbankcomputing.co.uk/software/pyqt/download5

There are also run file downloads, http://qt-project.org/downloads

Source or./configure & make & sudo make install. If it is run, add the X permission first.

Sudo chmod + x **. Run

After installation, add the path to the environment variable ~ /. Bash_profile, mine is

export PATH=$PATH:/opt/Qt5.3.1/5.3/gcc_64/bin

sudo ln -s /opt/Qt5.3.1/5.3/gcc_64/bin/qmake /usr/local/bin

2.3 pyqt5 install

To install pyqt5, you need the above sip and qmake. Therefore, you need to install qt5 first.

Replace the following qmake with your directory and site-packages/, that is, the package location, and then compile

$python configure.py

Install

sudo make && sudo make install

A simple example is as follows:

import sys from PyQt5  import QtCore, QtGui, QtWidgets if __name__ == ‘__main__‘:    app = QtWidgets.QApplication(sys.argv)    w = QtWidgets.QWidget()    w.resize(250, 150)    w.move(300, 300)    w.setWindowTitle(‘Simple‘)    w.show()    sys.exit(app.exec_())

If any compilation error occurs, try

sudo ARCHFLAGS="-Wno-error=unused-command-line-argument-hard-error-in-future"

Add the command
