Suggestion: make `Cartopy` and opt-in dependency
As of 0.7.7, Cartopy is a required dependency of nvector. This is sometimes problematic since Cartopy does not provide ready-built wheels on pypi, thus requiring every user to have a proper build environment (including a build of GEOS) to do pip install nvector.
My suggestion would be to put the plotting part of nvector as a an optional dependency so that users can do pip install nvector to get the core functionality or pip install nvector[plots] (or similar) to also require Cartopy (and perhaps matplotlib).
Right now, the "easy way out" for me is to do: pip install "nvector<=0.7.6"
Hello @freol35241,
I have taken the liberty to fork the nvector package into a new PyPI package titled envector. The envector package is intended as a drop-in replacement with minimal changes in your source code as no methods and classes have been removed since the fork. For example, this is a valid snippet
import envector as nv
wgs84 = nv.FrameE(name='WGS84')
As for this issue, I believe you have a valid point. I think this change is appropriate for "envector" and welcome the suggestion. I politely request that open the same issue at the envector homepage in order for the package to get more public awareness.
Thank you for your attention.
EDIT: The envector package dependency specifications set Cartopy>=0.22.0", which include wheel files. With that said, Cartopy should not be strictly required as the case when it is missing is supported in both nvector and envector.
