Error => line:0 the the design mode requires a valid Qt kit.(PySide6)

[SGaist]

Did you configure your Python environment properly ?
Did you select one that contains your installation of PySide ?

[Abdullah.S]

@SGaist yes, I did

[Abdullah.S]

@SGaist it still does not work

[SGaist]

Can you show your configuration ?
Are you using a virtual environment ?

I'm using PySide2. Same issue here.

Qt Creator 5.0.2
Based on Qt 5.15.2 (MSVC 2019, 64 bit)

I tried with different versions of Python with PySide2 installed. To verify, when I click run button, the application is launched and working properly.
When I try to edit QML files in Design Mode, I get the error:

Line: 0: The Design Mode requires a valid Qt kit.

@SGaist Maybe i misunderstood you, but I will share the images of kits and python
settings.

.

and this is my text edit's beginning

Thank you for your interest

[SGaist]

The message looks like related to your emscripten kit. Are you going to develop for it ?

[Abdullah.S]

@SGaist said in Error => line:0 the the design mode requires a valid Qt kit.(PySide6):

Are you going to develop for it

I couldn't understand,I really do not know what emscripten kit is. Should I delete something or install something ?

[SGaist]

This is the webassembly kit.

If you don't know what I am talking about, I would recommend that your remove all Qt versions that you are not going to develop with.

[Abdullah.S]

@SGaist I removed them but it still gives me the error

[SGaist]

What do you have now in the Python part ?

[Abdullah.S]

@SGaist

if you are talking about this, this is the same as before

[Abdullah.S]

guys I solved the problem. The problem was actually very simple. only you need to check the kits if their qt version is right or not. For example I use Desktop (x86-darwin-generic-mach_o-64bit) kit for my Qt Quick and when I scroll down the kits page there is qt version for the kit you selected, there are some options; "none", "Qt 6.2.3 for macOS", "Qt 6.2.2 (6.2.2)...." and you should choose the right one. thanks for all your help.

@Abdullah-S
Thanks！
This solved my probem, and it's that simple!!!
I installed qt coorectly, and python、Pyside6, So the solution is just like Abdullah said:
GO to Preferences -> Kit-> Auto-detected Qt -> scroll down-> Qt version->select the version.

Thanks again!
