PySide6: error while loading shared libraries: libQt6DesignerComponents.so.6: cannot open shared object file

I'm trying to run QT Designer from the terminal

pyside6-designer

but get the error message:

venv/lib/python3.8/site-packages/PySide6/designer: error while loading shared libraries: libQt6DesignerComponents.so.6: cannot open shared object file: No such file or directory

Inspecting the folder, I can confirm libQt6DesignerComponents.so.6 exist in the folder:

/venv/lib/python3.8/site-packages/PySide6/Qt/lib

I have re-installed and also tried the alternative PIPENV, but same result. Trying to execute in the same folder it ask me to install qtchooser. But didn't work after installing this.

I am on Ubuntu 20.04. I can find a ticket saying it should be solved. link to solution

I have also tried some random stuff, such as

sudo /sbin/ldconfig -v

which is described here its foss. It didn't work.

Anyone got experience of the same problem and have a solution?

Solution

  • Set your LD_LIBRARY path in shell (bash) after activating a venv:

    export LD_LIBRARY_PATH=/home/FILL_IN_USERNAME/PycharmProjects/pythonProject/venv/lib/python3.8/site-packages/PySide6/Qt/lib/

    I'm running Kubuntu Groovy Gorilla.

    I'm quite excited about trying this out.
