i have a problem with PyQt5 Designer. I install PyQt with -pip install PyQt5 and then -pip install PyQt5-tools
everything OK. But when i try to run Designer it open messagebox with error: This application failed to start because no Qt platform plugin could be initialized!
how to deal with it?
Try running it using command: pyqt5designer
It should set all the paths for libraries.
Works on Python 3.8, pyqt5-tool 5.15
PyQt5 Designer is not working: This application failed to start because no Qt platform plugin could be initialized
