First Steps in Qt Creator: ModuleNotFoundError: No module named 'PyQt5' - beginners issue

NewProgrammer

Hi there,

I am new to Qt. I downloaded and installed Qt from the website. I developed my application in Python, through Spyder IDE. Now i want to make the interface using Qt creator.

Situation:

Installed Qt.
Run the most basic example available online (https://doc.qt.io/qtforpython/tutorials/qmlapp/qmlapplication.html)
Receive the following error: ModuleNotFoundError: No module named 'PyQt5'

More info:

Pip list: PyQt5 5.12 is installed. (no virtual environment in place)
Installed folder of PyQt5: "C:\Users{user}\AppData\Roaming\Python\Python38\site-packages\PyQt5\QtGui.pyd"
When running Qt: Kit: Desktop
Evaded PyQt5, used a different example with PySide6: similar issue: "ModuleNotFoundError: No module named 'PySide6'.

Further:

I checked Qt application to see if I may force the application to look at the PyQt5 folder for the module: I could not find a way to force Qt.
I checked QML2_IMPORT_PATH: but found no correct explanation on how to actually implement it..

What did I miss when Installing Qt?
How to solve this issue?

Thank you, Kind regards,

Ivo

Check your python path.
If you did pip install on a venv you should select it as the python interperter.
It would be nice if you will take screenshot of how you import and the above two suggestions

Thank you for your reply. I tried several solutions compared to last week.

Identified two python versions. So I created a new virtual environment.
I stopped with PyQt5 as I could not find an installation that seemed to work.
I installed and uninstalled python and PySide2: untill PySide worked on my IDE (Spyder), in versions: PySide2 5.13.2 and Python 3.6.13.
Set QT to look at the new virtual environment python.exe
In QT i was however still unable to run a simple example: I received DLL errors. Also, on the Spyder (IDE), when trying to view a qml example, there were no warnings, but also no pop-up. PySide2 without qml works however.

Any tips?

Thank you.

Kind regards,
Ivo
