[Qgis-user] Fw: QGIS in Conda env

[Roland Berger]

Hi

I just installed similar on linux mint. The default qca dependency is 
wired to QT6. But QGIS 3.4 is still on QT5. So you need a specific 
version of qca which has dependencies to QT5. Well, that is what claude 
told me. For me the following works:

 1. conda create -n qgis-344_py313 -c conda-forge qgis=3.44.9
    python=3.13.14 "qca=2.3.10=h71e8f01_0" -y
 2. conda activate qgis-344_py313
 3. conda run qgis

Hope this helps
Roland
