Fiona doesn't currently support GDAL 3.x. For now, if you want to use Fiona you're going to have to downgrade to 2.x.

I'm going to leave this issue open as this particular error is actually a problem with setup.py not handling the version number correctly, with an if-ifelse with no catchall else.

Fiona/setup.py

Lines 214 to 225 in d6ec15f

	shutil.copy('fiona/_shim1.pyx', 'fiona/_shim.pyx')
	shutil.copy('fiona/_shim1.pxd', 'fiona/_shim.pxd')
	elif gdal_major_version == 2:
	if gdal_minor_version >= 2:

Also just noticed the mixed use of gdalversion/gdal_major_version .

This is addressed by #804.
