What is the correct (to work) way to install PyQt GPL5.6?

Question

Python

The application does not start because it could not find and start Qt.

Following the instructions from the Internet:
- Installed the PyQt5 module.
- installation PyQt GPL5.6 installed.
PyCharm defines PyQt5 but does not define imported widgets. With all this, when you try to run an example from the Internet, the above window pops up.
I launch PyQt Examples and the same window pops up.
Reinstalling, as advised, does not change anything. Creative experiments with changing the installation path also ended in failure. Message

Avaible platform plugins are: minimal, offscreen, windows

I didn't understand.
Is there a solution to the problem with this window?

Answer 1

Try installing the PyQT library, as well as the Qt Designer utility using the standard pip package manager:

pip install --upgrade pip
pip install pyqt5 pyqt5-tools

I did the installation for myself in this way and got acquainted with PyQT. At the same time, if you need Qt Designer for visual design of forms, then it will be available approximately along the following path:
C:\Users\<Your user>\AppData\Local\Programs\Python\Python36\Lib\site-packages\pyqt5- tools\designer.exe
But personally, I advise you to describe the molds manually, at first it is difficult, but then it becomes easy, fast and understandable =)
