Python Path Environment not correctly set on fresh install (geopandas cannot be imported, fiona not found) #46879

Closed wmeinolf closed 2 years ago

What is the bug or the crash?

On a new PC we installed QGIS using OSGeo4W Installer and found, that some processing scripts did not load. Same worked fine on former installations end 2021. Missing processing scripts use geopandas. During tests we found, that installed geopandas lib cannot be imported.

Steps to reproduce the issue

(1) Install QGIS using OSGeo4W Installer with admin rights, easy install and select QGIS, Grass and Saga. (2) Start installer again and add python libs rtree and geopandas. Confirm, to also install dependent packages, which include fiona. (3) Start QGIS (4) Start pyqgis Console (5) Enter "import geopandas", first error ist displayed (4) Enter "import geopandas" again, different error ist displayed

Hi Team, we finally found a workaround / solution. The current OSGeo4W installer seems not to set all environment variables.

Solution/Workaround: Execute manually the python-qgis.bat located in OSGeo4W\bin folder. Close window with exit().

Alternatively also "set PYTHONPATH=%OSGEO4W_ROOT%\apps\qgis\python;%PYTHONPATH%" entered in OSGeo4W Shell seems to help.
