Problem installing apstools

[gfabbris]

I could not install apstools=1.4.1 in my computer through conda. Then I cloned it, and tried to create a fresh environment for it using conda env create -f environment.yml, this also failed (it reported a horrible list of conflicts). It turns out the source of the conflicts seem to be hklpy. I removed it from "environment.yml", and it installed fine. Then:

$ conda activate apstoolsdoc
$ conda install -c nsls2forge hklpy

Same happens if I do $ conda install -c aps-anl-tag apstools.

The issue seems to be that the hkl package is for linux only. This breaks the hklpy, and then apstools, installation.

I was running into this yesterday for 30-ID. Had to explicitly install gobject-instrospection (needed by hklpy).

[gfabbris]

Just for some background, I was trying to install it in my Macbook. I installed gobject-instrospection, and doesn't work. I tried installing it in a linux and it worked fine. So I think the problem is really the dependency on the hkl package (https://anaconda.org/nsls2forge/hkl).

apstools will mostly be used at the beamlines, so this should be fine. But we could add some warning that hkl is not required, but needed to use apstools.diffractometer.

Definitely will need the underlying compiled hkl C++ library to be installed by some mechanism. It's only compiled for linux in the conda package. Compilation process is more tedious than many packages.

[prjemian]

Since all the diffractometer support is planned to move into hklpy, that dependency can be removed once the code is moved.

If the code is removed now, then the hklpy addition will need to retrieve the code from the 1.4.1 release here.
