BUG: conda install requirement of apstools>=1.5.3 fails on Windows - pip successful

[prjemian]

Discovered that with a conda install requirement of apstools>=1.5.3, conda was not able to resolve all dependencies for Windows. (Found this by selective removal of packages from environment until successful install.) Was able to install latest apstools via pip.

Is it because of aps-dm-api? #561

[prjemian]

That is a distinct possibility, which would push this to the 1.6.0 since it would mean a breaking change.

I install the mac version on my mac and that worked (I have apstools 1.5.3);

@rodolakis: Thanks!

@rodolakis: what is your python version? The 1.5.3 does install in my Mac, but only if python <= 3.7. Even if I install it in an environment with a newer version, conda will downgrade it to 3.7.

[rodolakis]

I'm all good, I was just not running what I thought (too many aliases, config etc...)

[prjemian]

See if the 1.5.4 release fixes this. Pushing to the next milestone after the 1.5.4 release.

Released 1.5.4 yesterday. Try again in Anaconda Powershell prompt:

conda create -n test "apstools>=1.5.3" -c defaults -c conda-forge -c aps-anl-tag

Still a problem:

Pin the python version, still fails:

[prjemian]

To test, a tag is necessary: 1.6.0rc#

[prjemian]

Tagged 1.6.0rc3 to test in windows. Once that publishes to anaconda.org, then test with:

conda create -n test "apstools=1.6.0rc3" -c defaults -c conda-forge -c aps-anl-tag

[prjemian]

This worked but apstools>=1.6 failed. Probably because only release candidates are available.

conda create -n test "apstools>1.5.4" --force -y -c defaults -c conda-forge -c aps-anl-tag

This worked!
