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

[Abdullah.S]

I reinstalled Qt Creator. Before I delete it, it was working without error but now I cannot use form editor when I click on form editor it gives me this error: line:0 the the design mode requires a valid Qt kit. I cannot use form editor but when I run the application it runs. I need help as soon as possible, thanks in advance.

Hi,

Which version of Qt Creator ?
On which OS ?
How did you install it ?
Do you have at least one kit ?
How did you setup your project ?
How did you install PySide6 ?

[Abdullah.S]

@SGaist Qt Creator 6.0.2
Based on Qt 6.2.2 (Clang 12.0 (Apple), 64 bit)
on macOs
I installed it from open source
yes I have kit
I clicked new project- Qt for python- Qt Quick application
I wrote "pip3 install PySide6" on terminal

@SGaist please do not forget to reply this question I also have the exactly same issue.

[Kullanici]

@SGaist why no one cares about this :(

[Abdullah.S]

@SGaist sorry but can you tell me if you do not know the solution, I have been waiting for an answer. I know you are trying to help me so thanks anyway but please just tell me if you do not know the solution. Thank you.

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.

[Abdullah.S]

@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

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.
