The first question is which conda channel are you using? The correct
channel is "conda-forge" and this channel definitely has 2.3.0 as the
latest version for Windows 10 - see
https://anaconda.org/conda-forge/pdal
If you are not sure or are using another channel - remove pdal from your
conda environment and re-install with `conda -c conda-forge install pdal`.
If the channel is correct - then most likely you have something installed
in your environment that requires a version of one of the dependencies at a
lower version than is supported by version 2.3. The PDAL version 2.3
dependencies are :
curl >=7.77.0,<8.0a0, draco, geos >=3.9.1,<3.9.2.0a0, geotiff
>=1.6.0,<1.6.1.0a0, hdf5 >=1.10.6,<1.10.7.0a0, jsoncpp >=1.9.4,<1.9.5.0a0,
laszip, laz-perf, libgdal >=3.3.0,<3.4.0a0, libkml >=1.3.0,<1.4.0a0, libpq
>=13.3,<14.0a0, libxml2 >=2.9.12,<2.10.0a0, nitro, numpy, pkgconfig,
postgresql, sqlite >=3.35.5,<4.0a0, tiledb >=2.3.0,<2.4.0a0, vc
>=14.1,<15.0a0, vs2015_runtime >=14.16.27012, zlib >=1.2.11,<1.3.0a0, zstd
>=1.5.0,<1.6.0a0
the easiest way to check might be to create a new, clean environment, add
PDAL (you should get version 2.3) and then incrementally add the packages
you need until you get a version clash reported (or something forces a
downgrade of PDAL - you should see this in the messages from `conda
install`).
