[gdal-dev] gdal_calc.py Does Not Work on Mac

[Andreas Oxenstierna]

Hi

My gdal installation with brew, https://formulae.brew.sh/formula/gdal,  do work on macOS:
which gdal_calc.py
/usr/local/bin/gdal_calc.py

ls -l /usr/local/bin/gdal_calc*
/usr/local/bin/gdal_calc.py -> ../Cellar/gdal/3.3.2_3/bin/gdal_calc.py

Do you have to use Anaconda?

Best Regards
