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

SGaist

Hi,

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

@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?

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

SGaist

Might be the space in the path.

I know it is looks like not an answer but stupid mistake, but I step on that rakes ones again and according to some questions on "StackOverflow" not only me.
I placed .exe file alongside with all .dlls by windeployqt and with folder plugins containing my plugin. The problem appears when I load plugin in my app. Solution is pretty simple: I run windeployqt for my .exe but my plugin.dll requires own specific dlls and I didn't place them along. Putting all .exe's and plugin's dlls together helped me to get rid of that message.
