Environment.yml use for a Mac

[jomey]

Not an issue for the Docker and Linux environments and when people try to re-use the environment.yml to replicate it on a Mac, they will fail with this entry:

python-pdal=2.4=py38h1fd1430_1

The hash at the end seems to be version specific to the Linux version.

right. PDAL was a pain to install, had to use that specific version for the import to work (#12). I think running via docker is the only surefire way to get the same environment, but you can also try using https://github.com/conda-incubator/conda-lock to export lock files for each OS... probably do need to drop any specific build hashes though.

You can loosen the hash restriction and just pin it down to that version

python-pdal=2.4

That will work for all OSes and only get that published one. The hash will pin it down to flavor and version of OS.

For completeness, this would be the corresponding Mac version:

 osx-64/python-pdal-2.4.0-py38h12bbefe_1
