Solution 1

Today I found the solution. The steps below worked for me, without any error. The whole process took almost two hours.

sudo apt-get update
sudo apt-get install qt5-default
sudo apt-get install sip-dev

cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-4.19.14.tar.gz
sudo tar xzf sip-4.19.14.tar.gz
cd sip-4.19.14
sudo python3.6 configure.py --sip-module PyQt5.sip
sudo make
sudo make install

cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5_gpl-5.12.tar.gz
sudo tar xzf PyQt5_gpl-5.12.tar.gz
cd PyQt5_gpl-5.12
sudo python3.6 configure.py
sudo make
sudo make install

Solution 2

Seems like they moved some things around. This seems to work, as far as getting things, and compiling them. It takes a long time to build.

For the associated designer, look at:

QtDesigner for Raspberry Pi

sudo apt-get update
sudo apt-get install qt5-default
sudo apt-get install sip-dev

cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/4.19.23/sip-4.19.23.tar.gz
sudo tar xzf sip-4.19.23.tar.gz
cd sip-4.19.23
sudo python3 configure.py --sip-module PyQt5.sip
sudo make
sudo make install

cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/5.13.2/PyQt5-5.13.2.tar.gz
sudo tar xzf PyQt5-5.13.2.tar.gz
cd PyQt5-5.13.2
sudo python3  configure.py
sudo make
sudo make install

Since I found no answer for my question, neither in older posts nor in other forums, I want to ask the stackoverflow community for advice.

I am using a raspberry pi 3B+, version 9.4 (lite) with kernel version 4.14.71-v7.

I use python3.6. I installed it as follows:
```
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

cd /usr/src
sudo wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
sudo tar xzf Python-3.6.0.tgz

sudo -s
cd Python-3.6.0
bash configure
make altinstall
exit
```
Installation was without any trouble and everything works perfectly.

Now I wanted to install the PyQt5 modul for python3.6. I usually use
```
sudo python3.6 -m pip install ...
```
for installing a modul for python3.6. Trying
```
sudo python3.6 -m pip install pyqt5
```
gave me the error message
```
 Could not find a version that satisfies the requirement PyQt5 (from versions: )
 No matching distribution found for PyQt5
```
So I tried
```
sudo apt-get update
sudo apt-get install qt5-default pyqt5-dev pyqt5-dev-tools
```
But it installed PyQt5 for python3.5 (which is preinstalled) on the raspberry.

So does anybody know how to use or install PyQt5 for the subsequently installed python3.6?

Edit 08.03.2019:
Thanks FlyingTeller. I started to build from source. I followed the steps from your link.
```
sudo apt-get update
cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/sip/sip-4.19.14.tar.gz
sudo tar xzf sip-4.19.14.tar.gz
cd sip-4.19.14
sudo -s
python3.6 configure.py --sip-module=PyQt5.sip 
make
make install

cd /usr/src
sudo wget https://www.riverbankcomputing.com/static/Downloads/PyQt5/PyQt5_gpl-5.12.tar.gz
sudo tar xzf PyQt5_gpl-5.12.tar.gz
cd PyQt5_gpl-5.12
python3.6 configure.py
```
Then I received the following error
```
Error: Use the --qmake argument to explicitly specify a working Qt qmake.
```
I think I am on the right way, but I do not understand what qmake is or what it means.

Edit 10.03.2019:
I could solve the last error message. I installed
```
sudo apt-get install qt5-default
```
Then I did the same procedure as already mentioned. Now I get the error
```
fatal error: sip.h: File or directory not found 
#include <sip.h>
```
PyQt5 config.py is in: /usr/src/PyQt5_gpl-5.12
SIP sip.h is in: /usr/src/sip-4.19.14

Anybody an idea? Thanks guys.

  Have you considered building from source?

  I am trying it but it has not worked yet. Check out the edits.

you would better use "sudo make -j4"

Why is that better?

By using "-j4" flag will increase the installation speed.
Totoro about 2 years

just for the benefit of someone who is curious, -j4 will divide the task to four CPU cores, thereby making teh installation faster.
