PyQt5 on a Raspberry Pi

You can try steps mentioned below. It will take some time to make and make install. Please be patient.

sudo apt-get install qt5-default

wget https://www.riverbankcomputing.com/static/Downloads/sip/4.19.24/sip-4.19.24.tar.gz

tar -xzvf sip-4.19.24.tar.gz

cd sip-4.19.24

python configure.py

make

make install

---

cd ../

wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5-5.15.1.dev2008081558.tar.gz

tar -xzvf PyQt5-5.15.1.dev2008081558.tar.gz

cd PyQt5-5.15.1.dev2008081558

python configure.py

make

make install

---

pip install PyQt5-sip

I can't leave a comment, not enough reputation, but thought I should mention this in case it helps anyone using VirtualEnv:

In my case (Raspbian on a Raspberry Pi 3, Python 3 in a virtual environment) the answer provided by CharlieHorse is the only one which worked as I could not get

sudo apt-get install

to install into virtual environments. I tried something like this question on Stack Overflow but because PyQt5 relies on SIP which interfaces with some C code, it needs to be compiled from scratch and can't just be copied, as recommended in the accepted answer of that question.

In Raspbian Stretch Lite the following worked for me:

sudo apt-get update
sudo apt-get install qt5-default pyqt5-dev pyqt5-dev-tools

I developed a similar application using PyQt4 and Qt4-designer. You have to install pyqt4 all modules:

sudo apt-get install qt4-default qt4-designer qt4-doc qt4-dev-tools python-qt4

So in your case just change all 4-5 i.e qt4 -- qt5.

OK... I managed to get this to work. This is what I did.

1. QT Core needs to be installed with

   sudo apt-get install qt5-default

2. You'll need to copy over sip and PyQt5 to your Raspberry Pi (I used SFTP). Just put the tar files someplace that you can get to them easily.

3. You'll need to extract each of them, using the tar command, with the -xzvf tag so you'll end up with tar -xzvf sip-4.19.1.tar.gz`for sip.

4. In each folder, you'll need to set up for the build. This is done by typing "python config.py" in each directory.

5. The contents of each directory needs to be built and installed, go to your sip folder and type "make" this will take a very long time. After it's through, type "sudo make install".

6. Now do the same thing in your PyQt5 directory.
