How to install PyQt5 in Python 3 (Ubuntu 14.04)

Online I find the following steps: http://pyqt.sourceforge.net/Docs/PyQt5/installation.html But they are too many. What’s the easiest way to Install PyQt5 along with Python3 in Ubuntu 14.04 ?

The install process went ok. But got runtime error QtCore.so: undefined symbol: PySlice_AdjustIndices

Why not simply install it via apt-get?

sudo apt-get install python3-pyqt5 

Otherwise you’d have to compile PyQt (and potentially Qt) by hand, which is cumbersome.

Well I documented the steps for Installing pyqt5 with qt designer and code generation here: https://gist.github.com/1dcd57542bdaf3c9d1b0dd526ccd44ff

Installation

pip3 install --user pyqt5 sudo apt-get install python3-pyqt5 sudo apt-get install pyqt5-dev-tools sudo apt-get install qttools5-dev-tools 

Configuring to run from terminal

$ qtchooser -run-tool=designer -qt=5 

Write the following in /usr/lib/x86_64-linux-gnu/qt-default/qtchooser/default.conf

/usr/lib/x86_64-linux-gnu/qt5/bin /usr/lib/x86_64-linux-gnu 

Code Generation

#!/usr/bin/python3 import subprocess import sys child = subprocess.Popen(['pyuic5' ,'-x',sys.argv[1]],stdout=subprocess.PIPE) print(str(child.communicate()[0],encoding='utf-8')) 

Create a symlink:

$ sudo ln uic.py "/usr/lib/x86_64-linux-gnu/qt5/bin/uic" 

Desktop Entry

[Desktop Entry] Name=Qt5 Designer Icon=designer Exec=/usr/lib/x86_64-linux-gnu/qt5/bin/designer Type=Application Categories=Application Terminal=false StartupNotify=true Actions=NewWindow Name[en_US]=Qt5 Designer [Desktop Action NewWindow] Name=Open a New Window Exec=/usr/lib/x86_64-linux-gnu/qt5/bin/designer 

save in ~/.local/share/application with .desktop extension

pip3 install —user pyqt5 will most likely throw Could not find a version that satisfies the requirement sip>=4.19.1 . I’m installing it from a fresh Linux installation.

How to install PyQt5 in Python3

Just installing it did not work for me. I had to uninstall it first, then reinstall it:

# upgrade pip python3 -m pip install --upgrade pip # uninstall python3 -m pip uninstall PyQt5 python3 -m pip uninstall PyQt5-sip python3 -m pip uninstall PyQtWebEngine # reinstall python3 -m pip install PyQt5 python3 -m pip install PyQt5-sip python3 -m pip install PyQtWebEngine
