conda-forge says us package incompatible with python 3.8

[ggordn3r]

I see you guys added support for Python 3.8 in version 2.0.0, but still got this error in conda today (after solving the base environment for an age):

UnsatisfiableError: The following specifications were found to be incompatible with the existing python installation in your environment:

Specifications:

• us -> python[version='2.7.|3.5.|3.6.|3.4.']

Your python: python=3.8

If python is on the left-most side of the chain, that's the version you've asked for. When python appears to the right, that indicates that the thing on the left is somehow not available for the python version you are constrained to. Note that conda will not change your python version to a different minor version unless you explicitly specify that.

I'm running conda 4.8.4 and tried both conda install us and conda -c conda-forge us since I saw a bug suggesting I might need to specify the channel. Same message both times.

Not sure if this is something on your side or conda-forge not using the latest version. I succeeded in 2 seconds with pip install us. Let me know if I should be reporting this to conda instead.

Update: looks like conda-forge is still trying to use 1.0.0, no wonder:

Same issue here There's this PR that updates the conda-forge version but it needs attention https://github.com/conda-forge/us-feedstock/pull/4

Same issue here, this causes dependency errors, possibly resulting from jellyfish (?) The automated update in conda-forge/us-feedstock#4 should be merged in.

Note that strict channel priority may have removed packages required for satisfiability.
