Installation fails when following instructions

[iancrossfield]

In a clean new conda environment, installation fails using the instructions on the docs page. The final error after pip install jmespath and then pip install exotedrf is

ERROR: Cannot install exotedrf==1.4.0 and exotedrf==2.0.0 because these package versions have conflicting dependencies.

The conflict is caused by: exotedrf 2.0.0 depends on ray exotedrf 1.4.0 depends on ray ... but no guidance is provided on what ray refers to.

The full error trace is below.

The conflict is caused by: exotedrf 2.0.0 depends on ray exotedrf 1.4.0 depends on ray

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict

Hi Ian, I'm not able to reproduce this error, either on Mac or Linux. The installation proceeds without issue in a fresh conda env in both cases.

I'm really in trouble then, I guess! Thanks -- we'll continue to troubleshoot.
