Installation error on Windows - ERROR: A GDAL API version must be specified

[amsantac]

Hi. Thanks for developing this plugin. Very promising!

I tried to install on Windows following your instructions. I did steps 1-3 without problem.

After running step 4 I get the following error:

ERROR: Command errored out with exit status 1: command: 'c:\osgeo41\bin\python3.exe' 'C:\OSGEO41\apps\Python37\lib\site-packages\pip_vendor\pep517_in_process.py' get_requires_for_build_wheel 'C:\Users \AL61EE1\AppData\Local\Temp\tmp3oe9w1vb'
cwd: C:\Users\AL61EE1\AppData\Local\Temp\pip-install-4i3dj5te\rasterio
Complete output (2 lines):
INFO:root:Building on Windows requires extra options to setup.py to locate needed GDAL files. More information is available in the README.
ERROR: A GDAL API version must be specified. Provide a path to gdal-config using a GDAL_CONFIG environment variable or use a GDAL_VERSION environment variable

I googled this error and some of the proposed solutions suggest to remove GDAL and reinstall geopandas. I am not sure if that's a good idea or how to do that or if the problem is due to rasterio. Other package developers try to remove the geopandas dependency.

I'd appreciate any help to solve this issue.

Thanks!

With the current QGIS it looks like you need to do this for a start: set GDAL_VERSION="3.5.1"
But some setup for a c++ compiler seems to be needed too:

      copying .\fiona\fio\__init__.py -> build\lib.win-amd64-3.9\fiona\fio
      running build_ext
      building 'fiona.schema' extension
      error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
