I used conda to install GDAL in a virtual environment in OSX 10.15 (Catalina). I have no problem running the GDAL scripts in terminal (such as gdal_translate, gdalwarp, etc). I also installed QGIS (3.14.16-Pi). But I get an error when trying to run a QGIS command that calls GDAL.

For example, clipping a raster to a shape file using Raster > Extraction > Clip by Mask Layer yields the errors:

/bin/sh: gdalwarp: command not found

Following this post I prepended the path to gdal in QGIS: Preferences > System > Environment. But the problem remains.

Is there some other QGIS parameter I need to set to get it find gdal?

Installing GDAL:

conda create -n gdal_env
conda activate gdal_env
conda install gdal

gdalinfo --version
GDAL 3.0.4, released 2020/01/28

Path to GDAL prepended in QGIS:

/Users/MF/miniconda3/envs/gdal_env/bin

  • I should have mentioned that I restarted QGIS after prepending the path
