How to fix qt.qpa.plugin: Could not find the Qt platform plugin "windows" in "" error

SGaist

I did not write about "virtual environments" but about "environment variable".

@SGaist I did what you said and got this message
QFactoryLoader::QFactoryLoader() checking directory path "C:/Users/GOKTUº ALKAN/AppData/Local/Programs/Python/Python310/platforms" ...
qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Hi,

You should have had way more messages than that. There should be a full plugin dump.

Gokalp

@SGaist Thats all i got. Maybe i'm doing something wrong? i used this: os.environ["QT_DEBUG_PLUGINS"] = "1"

This is not going to work this way.
Set it in a terminal and then start your app in this terminal.

How can i set it in the terminal?

jsulm

@Gokalp On Windows:

set QT_DEBUG_PLUGINS=1

Gokalp

@jsulm still the same

SGaist

Can you retry with an environment stored in a path without space or accented character ?

Gokalp

@SGaist How can i do that? My brother happened to be at home when this pc arrived so he made the username his name which contains Ö and Ğ characters... I tried to change the username several times but it never changed on the terminal so i really don't know what to do. Maybe there is another way that i can do what you're saying?

SGaist

Install your python environment in a folder starting from the root of your disk. For example "C:/Code/name_of_your_environment".

Gokalp

@SGaist Could you tell me how to do that? I have never used python that way since i didn't face any problems before

SGaist

How did you install Python ?
How are you managing your virtual environments ?

Gokalp

@SGaist I have never messed with environments, i installed python from its site and used it globally. All of my modues are also installed globally.

SGaist

Then I would recommend reconsidering that modus operandi.

Which site?
Using Python installer from official Python website allows you to select the installation folder.

Gokalp

@jsulm i installed it directly into the c folder

SGaist

So what happens now ?

Gokalp

@SGaist Will create an venv as soon as i understand how to do it and post the results for the pyqt5 debug

Gokalp

@SGaist I created a venv under c:/ directly and it worked perfectly but i'm still confused why it worked on a computer named Göktuğ bu not on this computer named GÖTUĞ ALKAN while both have utf-8 characters in them
