Invalid projection EPSG 54009

Problem description

When trying to re-project the polygon from EPSG:4326 to ESRI:54009, I get the following error:

CRSError: Invalid projection: +init=esri:54009 +type=crs: (Internal Proj Error: proj_create: cannot expand +init=esri:54009 +type=crs)

I can’t seem to figure out if I’m missing a definition or dependency of some kind. Some insight would be appreciated.

Thanks!

@daniel-j-h, the +init= syntax is deprecated. So, updating to avoid it is a good idea. I would recommend using always_xy=True in the transformer when updating.

@snowman2, that works great. Thank you for your help!
