What happened? What did you expect to happen?

I get this error when trying to install the geoschem-gcpy package from PyPI with pip:

[ip-172-31-41-231 ~]$ pip install geoschem-gcpy
Collecting geoschem-gcpy

ERROR: No matching distribution found for xesmf==0.5.1 (from geoschem-gcpy)

The installation fails because xesmf==0.5.1 (which is used by GCPy) was removed from the PyPI index.

What are the steps to reproduce the bug?

$ pip install geoschem-gcpy

Will you be addressing this bug yourself?

Yes

Additional information

A fix for this will require updating GCPy to use one of the "approved" versions of xesmf. Until then, users should follow these instructions:
